[multi-ASIC] BGP internal neighbor table support (#5520)

* Initial commit for BGP internal neighbor table support.
  > Add new template named "internal" for the internal BGP sessions
  > Add a new table in database "BGP_INTERNAL_NEIGHBOR"
  > The internal BGP sessions will be stored in this new table "BGP_INTERNAL_NEIGHBOR"

* Changes in template generation tests with the introduction of internal neighbor template files.
