When tunnels are not found in cache today, ITM does a dip into DS
and updates the cache accordingly. This cause stale entries
getting added into the cache.
This issue was observed when a tep delete command is executed:
1. ITM initiates delete process.
2. ITM removes the tunnel from the InternalTunnel cache.
3. Before the DS is cleaned up, we try to fetch tunnels from cache
   to process clearance of Alarm if any for that tunnel.
   As the cache does not have that specific tunnel; ITM
   repopulates the cache by doing a dip into the DS.
4. Thereby a stale tunnel gets added to the cache.

The fix is to dip into DS if the tunnel is not present in the
cache but not update the cache.

Raised review for the same.https://git.opendaylight.org/gerrit/78643
