Rename BashCompDirectives to ShellCompDirectives (#1082)

Browse source 
Since the completion directives will be used for all shells, and that
these names will be consumed by users, this is a more appropriate name.

When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
