lab: Update lab's description

lab is a command line utility for GitLab.  It does wrap around git
currently, however, that isn't lab's primary purpose.

Update lab's description.

Additional fix: Remove some dead code.
Additional fix: Warn git wrapper users that git wrap functionality will
eventually be removed.
