[autotest] Change cautotest-mysql to IP of cautotest-mysql.

This dodges flakey DNS lookups.  It also bypasses the niceities of
having a layer of indirection, given that our IPs changing hasn't been
entirely infrequent.  This is just a workaround until the reason for the
DNS lookup flake has been found and fixed.
