Implement the '--format' option provided by 'ref-filter'.
This lets the user list tags as per desired format similar
to the implementation in 'git for-each-ref'.

Add tests and documentation for the same.

Hmm, do we want "--format" added to "tag -l" and "branch -l" in the
first place?  Scriptors should be using "for-each-ref" plumbing in
the first place, and the point of unifying these three is to share
filtering features among them, which would make "for-each-ref" able
to express what the other two can do.  I'd hesitate to add too much
flexibility to "branch -l" and "tag -l" Porcelains to entice people
to script around them.
