[HBASE-7989] Client with a cache info on a dead server will wait for 20s before trying another one.

• Type: Bug

Description

Scenario is:

• fetch the cache in the client
• a server dies
• try to use a region that is on the dead server

This will lead to a 20 second connect timeout. We don't have this in unit test because we have this only is the remote box does not answer. In the unit tests we have immediately a connection refused from the OS.
