org.jboss.eap.qe.ts.common.docker.Docker prints directly to System.out

We should use and configure jboss-logging for this instead.

I remember we've discussed in scope of: #21 and decided to use simple System.out for docker. However I was proffering to use proper logging ;-)

[honza-kasik]

Ah, thanks - I missed that. The bare minimum I would like to tho is make the PrintStream which will be used configurable for now. WDYT @mnovak1 ?
EDIT: I would also like to remove the ANSI escape codes, so the possible transition to logger in future is more seamless.

I would prefer more proper logging. But let's have it just for docker as I don't see any other module which would have strong need for it.
