Subject: srv6: T591: initial implementation to support locator definition

VyOS CLI

set protocols segment-routing srv6 locator bar prefix '2001:b::/64'
set protocols segment-routing srv6 locator foo behavior-usid
set protocols segment-routing srv6 locator foo prefix '2001:a::/64'

Will generate in FRR

segment-routing
 srv6
  locators
   locator bar
    prefix 2001:b::/64 block-len 40 node-len 24 func-bits 16
   exit
   !
   locator foo
    prefix 2001:a::/64 block-len 40 node-len 24 func-bits 16
    behavior usid
   exit
   !
  exit
  !
 exit
 !
exit

(cherry picked from commit ca301cdd4746187f96ff84e411fda6a84e33f237)
