Fabric in the middle (#141)

* asynchronous create + l2sts for non cloud facility ports. Issue 89 and Issue 90

* adding support for l3vpn for non-cloud facility ports. Issue #138

* handling bidirrectional dependency. needed for chameleon network and fabnetv4

* initial support for cloudlab/chameleon nodes communicating via fabric l2sts

* tested old configs using stitch-info

* added stitching-chameleon-cloudlab-via-fabric config file
