to look at the new patch set (#3).
Change subject: [master] cache assigned locations

[master] cache assigned locations
This changelist adds a very primitive cache to master to cache
the location once assigned to tablet servers and clients.
The cache does not prevent running multiple commands for the same
location key if an entry is not present in the cache.
The idea is that we should not expect ConnectToCluster requests
from the same node running concurrently.
More advanced cache that takes care of the thundering herd pattern
is in the works, but I decided to put up this simple one as a first
step.
