6d2f1d2fa7 Ability to hide commands from usage/help text
Added the ability to have hidden commands that cobra will still run as intended, however they won't show up in any usage/help text

adding internal field to command

private is a better name

hiding private commands in default help/usage

opting for 'hidden' over 'private'

updating all 'help command' checks to exclude hidden commands

updating how commands are displayed in usage/help text by updating/adding some methods. added tests for hidden/deprecated commands

making command hidden when testing hidden command execution

test now leverage the included suite and are much less custom. also removed deprecation tests, once I discovered them in cobra_test.go

updating hidden command test to be more reliable

removing unnecessary () when checking len(c.Deprecated)

updating command comments to be godoc friendly

cfecf1379c manpage generation: Make sure parent in SEE ALSO has dashes
The CommandPath() for a parent might have a space (if .Parent() != .Root())
so we need to replace those spaces with `-`

5b121bc9fb Template Function Injection
This patch enables developers to add one to many template functions that
can be used by custom Usage and Help templates. Here is an example that
is included in the file cobra_test.go as the test function named
TestAddTemplateFunctions:

    AddTemplateFunc("t", func() bool { return true })
    AddTemplateFuncs(template.FuncMap{
        "f": func() bool { return false },
        "h": func() string { return "Hello," },
        "w": func() string { return "world." }})

    const usage = "Hello, world."

    c := &Command{}
    c.SetUsageTemplate(`{{if t}}{{h}}{{end}}{{if f}}{{h}}{{end}} {{w}}`)

    if us := c.UsageString(); us != usage {
        t.Errorf("c.UsageString() != \"%s\", is \"%s\"", usage, us)
    }

In the above example four functions are added to the template function
map used when the Usage and Help text is generated from the templates
that enable custom logic as well as data injection during template
execution.

e8bd799c1c Display pflag.CommandLine flags as if they were declared on the parent
```go
package main

import (
	"github.com/spf13/cobra"
	"github.com/spf13/pflag"
)

func main() {
	cmd := &cobra.Command{
		Use:   "min",
		Short: "minimal command",
		Run:   func(_ *cobra.Command, _ []string) {},
	}

	pflag.String("oncmdline", "oncmdline", "oncmdline")
	cmd.Execute()
}
```

Is a minimal cobra program.  When --help is displayed without this patch
you only get:

But with the patch --oncmdline is shows under flags.

07ad27d239 Handle grand children with the same name as the root
This fixes a problem where if you had a root command and a grand child
with the same name, the parser would break and would not run the
grandchild. The code was special casing if the immediate child had the
same name, but didn't handle grand-children

fb86c5c559 Correctly print the unknown command name
by now, if someone calls: `program --validflag unknowncommand` the
output will be:

```
Error: unknown command "--validflag"
Run 'program help' for usage.
```

This patch strips out flags so the unknown command is printed:

```
Error: unknown command "unknowncommand"
Run 'program help' for usage.
```

8a18f25809 Auto generation of markdown docs!
An example from the kubernetes project, for the `kubectl config`
command, which as subcommands, and flags, and all sorts of stuff, it
will generate markdown like so:

config modifies .kubeconfig files

config modifies .kubeconfig files using subcommands like "kubectl config set current-context my-context"

```
kubectl config SUBCOMMAND
```

```
      --envvar=false: use the .kubeconfig from $KUBECONFIG
      --global=false: use the .kubeconfig from /home/username
  -h, --help=false: help for config
      --kubeconfig="": use a particular .kubeconfig file
      --local=false: use the .kubeconfig in the current directory
```

```
      --alsologtostderr=false: log to standard error as well as files
      --api-version="": The API version to use when talking to the server
  -a, --auth-path="": Path to the auth info file. If missing, prompt the user. Only used if using https.
      --certificate-authority="": Path to a cert. file for the certificate authority.
      --client-certificate="": Path to a client key file for TLS.
      --client-key="": Path to a client key file for TLS.
      --cluster="": The name of the kubeconfig cluster to use
      --context="": The name of the kubeconfig context to use
      --insecure-skip-tls-verify=false: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
      --log_backtrace_at=:0: when logging hits line file:N, emit a stack trace
      --log_dir=: If non-empty, write log files in this directory
      --log_flush_frequency=5s: Maximum number of seconds between log flushes
      --logtostderr=true: log to standard error instead of files
      --match-server-version=false: Require server version to match client version
      --namespace="": If present, the namespace scope for this CLI request.
      --password="": Password for basic authentication to the API server.
  -s, --server="": The address and port of the Kubernetes API server
      --stderrthreshold=2: logs at or above this threshold go to stderr
      --token="": Bearer token for authentication to the API server.
      --user="": The name of the kubeconfig user to use
      --username="": Username for basic authentication to the API server.
      --v=0: log level for V logs
      --validate=false: If true, use a schema to validate the input before sending it
      --vmodule=: comma-separated list of pattern=N settings for file-filtered logging

5c9146990b Explicitly support local flags overwriting persistent/inherited flags
The current (desired) behavior when a Command specifies a flag that
has the same name as a persistent/inherited flag, is that the local
definition takes precedence. This change updates the various
Flag subset functions to respect that behavior:
* LocalFlags: now returns only the set of flags and persistent flags
  attached to the Command itself.
* InheritedFlags: now returns only the set of persistent flags inherited
  from the Command's parent(s), excluding any that are overwritten by a
  local flag.
* NonInheritedFlags: changed to an alias of LocalFlags.
* AllPersistentFlags: removed as not very useful; it returned the set
  of all persistent flags attached to the Command and its parent(s).

Default UsageTemplate updated to use LocalFlags and InheritedFlags

9b6c92647a When no subcommands are registered, omit command help output
For a single root command with a Run method, the help output still
contains 'help [command]' as a subcommand (because Help is always
added). Since the only subcommand would be 'help', the help is better
off omitted.

This change allows a command to be used both as a subcommand
or a root command without having to define a custom help that elides
the help command when no subcommands are added.  Instead, the default
help command is only added when subcommands are present.

667c348dbd Test behavior for subcommand with same name as root command
If, for some reason, you have an application with some name "foo", and your
app has a subcommand "foo", cobra should behave properly when you call
"foo foo", and it should also behave if you call "foo f".

These changes verify both of these cases and ensure cobra responds properly.
