List ha router count should not include dvr local router
Due to the class inheriting order the dvr local router will
be counted to the l3 agent restart query. This will cause
l3 agent run the ha port down action. This patch renames
the function to avoid that.

Title:
[L3][HA] agent HA router count should not include dvr local router
Status in neutron:
Fix Released
Bug description:
If dvr local router was processed in one l3 agent because it is
required by other functionality. For instance, DHCP agent for one
network will trigger L3 agent hosting the dvr_local router to it. If
the agent mode is `dvr_snat`, this dvr router will be counted to the
HA router list. This is not correct for l3 agent [1] during the
restart. Then the HA router related process count can not match the HA
router list. The HA port `DOWN` action will be triggered
unnecessarily. The issue is because function _get_router_ids_for_agent
[2] is overrided by [3] in for dvr. Such dvr local router will be
counted to the router ids list.
