When a command has set DisableFlagParsing=true, it means Cobra should
not be handling flags for that command but should let the command
handle them itself. In fact, Cobra normally won't have been told at all
about flags for this command.
Not knowing about the flags of the command also implies that Cobra
cannot perform flag completion as it does not have the necessary info.
This commit still tries to do flag name completion, but when
DisableFlagParsing==true, it continues on so that ValidArgsFunction will
be called; this allows the program to handle completion for its own
flags when DisableFlagParsing==true.

* Fix flag completion
The flag completion functions should not be stored in the root cmd.
There is no requirement that the root cmd should be the same when
`RegisterFlagCompletionFunc` was called. Storing the flags there does
not work when you add the the flags to your cmd struct before you add the
cmd to the parent/root cmd. The flags can no longer be found in the rigth
place when the completion command is called and thus the flag completion
does not work.
Also #1423 claims that this would be thread safe but we still have a map
which will fail when accessed concurrently. To truly fix this issue use a
RWMutex.

* Fix trailing whitespaces in fish comp scripts
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
zsh is now the default on Mac OS, but the $_fpath version of the installation instructions are likely to put the completion in a strange location that the user might not expect (e.g. an oh-my-zsh plugin's function directory). So, since Mac OS seems to (as far as I can tell) provide a stable location, this PR recommends using that path instead.
If the interspersed option is set false and one arg is already set all
following arguments are counted as arg and not parsed as flags. Because
of that we should not offer flag completion. The same applies to arguments
followed after `--`.

* Fix fish for ShellDirectiveNoSpace and file comp
For fish shell we achieve ShellDirectiveNoSpace by outputing a fake
second completion with an extra character. However, this extra
character was being added after the description string, instead of
before. This commit fixes that.
It also cleans up the script of useless code, now that fish completion
details are better understood.

* Update based on review
1- We use `set -l` for local variable to make sure there are no
conflicts with global variables
2- We use `commandline -opc` which:
a) splits the command line into tokens (-o)
b) only considers the current command (-p) (e.g., echo hello; helm <TAB>)
c) stops at the cursor (-c)
3- We extract the last arg with `commandline -ct` and escape it to handle
the case where it is a space, or unmatched quote.
4- We avoid looping when filtering on prefix.
5- We don't add a fake comp for ShellCompDirectiveNoSpace when the
completion ends with any of @=/:., as fish won't add a space

Fixes#1211
When handling ShellCompDirectiveNoSpace we must still properly handle
descriptions. To do so we cannot simply use 'compadd', but must use
zsh's '_describe' function.
Also, when handling ShellCompDirectiveNoSpace we cannot assume that
only a single completion will be given to the script. In fact,
ValidArgsFunction can return multiple completions, even if they don't
match the 'toComplete' argument prefix. Therefore, we cannot use the
number of completions received in the completion script to determine
if we should activate the "no space" directive. Instead, we can leave
it all to the '_describe' function.
Fixes#1212
When handling ShellCompDirectiveNoFileComp we cannot base ourself on
the script receiving no valid completion. In fact,
ValidArgsFunction can return multiple completions, even if they don't
match the 'toComplete' argument prefix at all. Therefore, we cannot use
the number of completions received by the completion script to determine
if we should activate the "no file comp" directive. Instead, we can
check if the '_describe' function has found any completions.
Finally, it is important for the script to return the return code of the
called zsh functions (_describe, _arguments). This tells zsh if
completions were found or not, which if not, will trigger different
matching attempts, such as matching what the user typed with the the
content of possible completions (instead of just as the prefix).

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`.
