For each plugin, helm registers a ValidArgsFunction which the completion
script will call when it needs dynamic completion. This
ValidArgsFunction will setup the plugin environment and then call the
executable `plugin.complete`, if it is provided by the plugin.
The output of the call to `plugin.complete` will be used as completion
choices. The last line of the output can optionally be used by the
plugin to specify a completion directive.

Allow plugins to optionally specify their sub-cmds and flags through a
simple yaml file.
When generating the completion script with the command
'helm completion <bash|zsh>' (and only then), helm will look for that
yaml file in the plugin's directory. If the file exists, helm will
create cobra commands and flags so that the completion script will
handle them.

When calling a plugin, if a global flag requiring a parameter was
missing the parameter, helm would crash.
For example:
helm 2to3 --namespace<ENTER>

Consistenly remove all arguments which are passed as environment
variables.
Get all arguments from environment variables passed to plugins.

* Add logic for platform specific commands to plugins
* Add plugins doc updated to incorporate platform specific commands
* Add condition for os match: If OS matches and there is no more specific match, the command
will be executed
It is now possible to create plugins with chart download capabilities for custom, non-http protocols.
Furthermore it is possible to reuse helm packages to implement alternative clients with these custom downloader functions.
Add plugin management subcommands for installing and removing plugins
to `$HELM_HOST/plugins`.
Install accepts a vcs url or a local directory.
```
$ helm plugin install http://github.com/adamreese/helm-env
Installed plugin: env
$ helm plugin list
NAME VERSION DESCRIPTION
env 0.1.0 Print out the helm environment.
$ helm plugin remove env
Removed plugin: env
