Difficult to distinguish pilot logs from the underlying database logs

[wallrj]

It's difficult to distinguish between the logs produced by the Pilot process and the logs from the database subprocess.

For example:

kubectl --namespace test-cassandracluster-1512066728-5581 logs cass-cassandra-1512066728-5581-cassandra-ringnodes-1
...

The last line is from Cassandra, but it's in a different format.

We could launch a goroutine to read from the stdout / stderr pipe of the process and feed it to glog.

Or we could reconsider a design where the database and the pilot run in separate containers, in which case there logs are kept separate anyway.
