Added option to enable/disable Static Route Advertisement (#9298)

Browse Source 
What I did:

Added option 'advertise':'true'/'false' to STATIC_TALE to control whether given route need to be advertise into BGP.

How I did:

Add a route in FRR with tag (1 for advertise and 2 for not advertise)
Create Route Map to match on tag as 1 and permit
Attach route-map to redistribute static.
Minigraph option to parse advertise option of Static Route.
