This commit add command to speficy SRv6 locator for BGP SRv6-VPN.
CLI example is follow. CLI block of "segment-routing" is already
implemented by previous commits and it's managed by zebra.
Zebra manage just the ownership of locator's prefix.
Zlient can request to get srv6-locator's prefix chunk using
srv6_manager_get_locator_chunk() which is usuful func to
execute ZEBRA_SRV6_MANAGER_GET_LOCATOR_CHUNK api. This request
is wokring as async, And zebra calls same api to Zclients when
zebra allocate locator prefix chunk.
And then, finally zclient(bgpd) catch the information via
process_srv6_lcoator_chunk callback function.

[POINT_OF_REVIEW]
In current implementation, user can just configure srv6 locator
but user can't de-configure srv6 locator.
