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
This is copied from web UI. We could check for uniqueness since we already get hold of all projects on server (can not guarantee update to date but still). Mentioning unique at least will let them aware they may see error coming from this.
