Update MySQL handler to add timeout for DNS query failures

Browse Source 
Signed-off-by: Michael Irwin <mikesir87@gmail.com>

I was helping troubleshoot an issue with someone, who ended up
having a typo in their compose file where the MySQL service was
using the name "msyql", which obviously causes DNS to fail. But,
since the db init doesn't time out, it just looks hung. This fixes
that.
