The default completion is useful also in cases where there are no
subcommands, for example to provide completion for flags, and custom
completions for their values.
But when there are no subcommands, make it hidden. Simply adding it
non-hidden would result in a help section to be added just for it which
is just noise: the completion command is not the primary functionality
of the program, yet it would be prominently displayed in help output. It
would also get included among argument completions, which could be a
source of confusion.
* Bash completion v2
This v2 version of bash completion is based on Go completions.
It also supports descriptions like the other shells.

Make it easier for programs to provide shell completion by creating
the 'completion' command automatically.
If a 'completion' command is already provided by the program, Cobra
will use that one instead.

The current powershell completion is not very capable.
Let's port it to the go custom completion logic to have a
unified experience accross all shells.
Powershell supports three different completion modes
- TabCompleteNext (default windows style - on each key press the next option is displayed)
- Complete (works like bash)
- MenuComplete (works like zsh)
You set the mode with `Set-PSReadLineKeyHandler -Key Tab -Function <mode>`
To keep it backwards compatible `GenPowerShellCompletion` will not display descriptions.
Use `GenPowerShellCompletionWithDesc` instead. Descriptions will only be displayed with
`MenuComplete` or `Complete`.

Replace the current Zsh completion with a Zsh completion solution based
on Go completions. This allows to support custom completions (based
on Go completions), but also to standardize the behavior of completion
across all shells.
Also, add support to Go completions for the bash completion annotations:
BashCompFilenameExt (including Command.MarkFlagFilename() family)
- still supported by zsh
BashCompSubdirsInDir - now supported by zsh
BashCompOneRequiredFlag (including Command.MarkFlagRequired() family)
- now supported by zsh and fish
Finally, remove the suggestin of the = form of flag completion.
The = form is supported, but it will not be suggested to avoid having
duplicated suggestions.
