Subject: T4163: Add BGP Monitoring Protocol BMP feature

Add BMP feature.
BMP (BGP Monitoring Protocol, RFC 7854) is used to send monitoring
data from BGP routers to network management entities

https://docs.frrouting.org/en/latest/bmp.html

Example:

set system frr bmp
commit
run restart bgp

set protocols bgp system-as '65001'
set protocols bgp neighbor 192.0.2.11 address-family ipv4-unicast
set protocols bgp neighbor 192.0.2.11 remote-as '65001'

set protocols bgp bmp mirror-buffer-limit '256000000'
set protocols bgp bmp target foo address '127.0.0.1'
set protocols bgp bmp target foo port '5000'
set protocols bgp bmp target foo min-retry '1000'
set protocols bgp bmp target foo max-retry '2000'
set protocols bgp bmp target foo mirror
set protocols bgp bmp target foo monitor ipv4-unicast post-policy
set protocols bgp bmp target foo monitor ipv4-unicast pre-policy
set protocols bgp bmp target foo monitor ipv6-unicast post-policy
set protocols bgp bmp target foo monitor ipv6-unicast pre-policy
