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 sentence is confusing. I suggest: "true|false. Whether to ask before performing an update." or something similar.
Another option, just separate the non-essential part behind a comma: "true|false. True to perform update checks without asking, when needed."
