When a user has an alias in powershell, she will need to register that
alias for completion. To make that possible, we store the completion
logic into a scriptblock variable which can easily be accessed by the
user to register aliases.
For example, if the user defines an alias for `helm`:
PS> sal h helm
she will need to register the alias like so:
PS> Register-ArgumentCompleter -CommandName 'h' -ScriptBlock $__helmCompleterBlock

* Bash completion v2
This v2 version of bash completion is based on Go completions.
It also supports descriptions like the other shells.

* Only consider matching completions for formatting

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.
