Fix Version/s: None
~/.my.cnf is used by css watcher, an optional tool used for monitoring css. It is a symlink to $QSERV_RUN_DIR/etc/my-client.cnf.
The css watcher could use MySQL credentials located in ~/.lsst/qserv.conf (used by integration tests wich are a Qserv/MySQL client)
In the grand scheme the watcher (if we ever manage to implement it) will be another service that runs alongside the worker mysql server. It should be treated like any other service - we'll need to provide an init.d script for it and
its configuration file(s) should be in the etc/ inside run directory, and not in user home directory.
