[frr] New Repository

[Donald Sharp]

All -

Martin has developed a topotest repository that runs some basic tests
against FRR.  Eventually I would like to get to a point where the CI
system autoruns these tests.  We as a group should also decide if we
want new features to include new tests for the feature as part of the
acceptance criteria.

The repository is at:

thanks!
