Enhancement - Delete Resource

[dgildeh]

We have the ability to import/export account resources using the cli but not the ability to delete a resource. Add a delete command which will remove both the local and remote resource from Outlyer:

outlyer delete {resource} --account={account-name}

This will confirm the action before applying it and deleting both the local file and the resource in the API. Note this command will work the same as the export/apply commands with how to select resources but will not allow the user to do a . resource to delete everything to avoid users accidentally deleting their entire account settings too easily.
