[NO TESTS NEEDED] This commit cleans up two issues: * Most commands support all EngineModes so default to that. Let outlayers declare their intent. * Use cobra.Annotations to set supported EngineMode. This simplies instantiating commands as there is now one method to communicate a commands requirements rather than two. * Combined aliased commands into one file * Fixed aliased commands where Args field did not match * Updated examples in README.md for writing commands * Remove redundant flag DisableFlagsInUseLine in cobra.Command initialization.

When a container is unmounted, the mount counter is decremented. The container's root filesystem is physically unmounted only when the mount counter reaches zero indicating no other processes are using the mount.
