Description

There are a couple of small in code, but significant in UX, improvement to the plugin download that need to be done.

• Have a default for the plugin folder on download ( should be ~/.config/ocm/plugins ( so --output is no longer required, filename could be the last segment of the plugin url ( because the resource name is binary always ) )
• Default it to ocmPlugin resource type and download it if it is alone so --resource-name is no longer required. ocmPlugin is the type of the resource and for a given architecture there needs to be only ONE.
• We don't have a list for plugins ( this is handled in Manage plugins for a plugin registry #600 )
• No help page for helm plugin

Done Criteria

• Plugin download command is super minimal
• Can call helmplugin --version to display information about the plugin
• Unit Tests created for new code or existing Unit Tests updated
• Successful demonstration in Review
