Check conf before restart

[auguster]

I just had a nasty crash of haproxy-consul because the data coming from consul led to a bad haproxy.cfg file. This caused haproxy to crash on restart, stopping the container.

I would be nice if haproxy-consul could check the config file (using haproxy -f /haproxy/haproxy.cfg -c) and if it's clean, only then restart haproxy. I would make the overall more robust and more trustworthy ;-)
