* FRR 4.0 integration with SONiC
-- Uses SONiC FRR repo frr/4.0 (which has SONiC support) to build image
-- Makefile changes to make frr4.0 builtable.
-- Updated/Added FRR configuration files
-- bgpd jinja template fixes
To build SONiC images with FRR4.0, simply edit rules/config file and change
routing stack to following:
SONIC_ROUTING_STACK = frr
and then build images as usual.
* Used integrated-vtysh-config in FRR
Changed to single template: frr.conf.j2 for configuration and added tests
