evicted flows in vrouter ideally should get removed on agent restart

[Vedamurthy Joshi]

R2.20 Build 112 Ubuntu 14.04 Juno multi-node

TCP evicted flows ideally should get flushed on agent restart
Functionally, it does not have any impact, but it is more of a consistency issue

root@nodek1:/var/log/contrail# flow -l --show-evicted | wc -l

root@nodek1:/var/log/contrail# service contrail-vrouter-agent restart

Reset evicted flows too at the time of soft-reset

Evicted flows, while active in the flow table, is not active in the
database used by entry allocator. The API that is used to get entries
that need to be reset returns only active entries in the allocator
database, thus excluding the evicted flows from the process of reset.
Introduce a new API that will return all entries that are active
in the flow table and use that api from the reset function.
