bgp: T4069: add "parameters fast-convergence" CLI option
Whenever BGP peer address becomes unreachable we must bring down the BGP session immediately. Currently only single-hop EBGP sessions are brought down immediately. IBGP and multi-hop EBGP sessions wait for hold-timer expiry to bring down the sessions. This new configuration option helps user to teardown BGP sessions immediately whenever peer becomes unreachable. This configuration is available at the bgp level. When enabled, configuration is applied to all the neighbors configured in that bgp instance.
