Enable entering sub commands in any order

[ericjaystevens]

Many subcommand are made up of a noun and action item. For example

/gitlab subscriptions list would also be written as /gitlab list subscriptions

I envision this being an option in the command definition file at the plugin level. something like interchangeableSubCommand = true. A more fine-grain approach identifying subcommands as either nouns or action items could add some value but probably overcomplicate things.
