[abessiari]

Note: Requires fablib extenstions 1.7.3

• using native providers
• stretch goal using sense

Initial support has been checked in
Requires fablib extenstions 1.7.3
More testing in progress is needed to make sure other examples work.

On fabric side a single l3vpn is created with both the gcp and aws facility ports.

Seeing issues with fablib 1.7.3 dx connection is named using the gcp pairing key. 1.6.4 is fine.
Looks like we need some changes in Fabric Control Framework (sliver.localname) and possibly in
AM handler ...

Tested after Komal's change in CF sliver.localname=slicename
