rhbz1110627 zanata init

https://bugzilla.redhat.com/show_bug.cgi?id=1110627
and https://bugzilla.redhat.com/show_bug.cgi?id=1038852

Depends on https://github.com/zanata/zanata-api/pull/15 and https://github.com/zanata/zanata-server/pull/520
One is warning one is question. I also try to make the question shorter so that their answer will stay in the same line as question.
