Spawned reconnect_loop process is not terminated when the client is terminated

[bjosv]

If an eredis client fails its first connection-attempt it will spawn_link a re-connection process.
This re-connection process will run until it succeeds.
But, if the connection attempts continuously fails and the user stops the eredis client, the spawned process is not terminated.
You will have an unexpected process running that attempts to connect to a previously used Redis instance.

A probable reason for this can be that eredis_client is stopped with reason normal, and an exit signal with reason normal is ignored by the re-connection process. See http://erlang.org/doc/reference_manual/processes.html#receiving-exit-signals
