COVERITY: Add coverity support
Using travis-ci we can start doing coverity scans on every pushed code.
This is not something new as so far we have been relying on sgallagh's
internal infra to do so, unfortunatelly the infra is about to be
retired ... thus, start to use public coverity's instance is a hard
requirement for us.
