BZ-1126497 - kie-config-cli: problems connecting in on-line mode

fixes to allow to use git ssh service from both regular git clients and kie-config-cli tool. Currently authorization will not be performed as there is no way to pass roles required for given repository/filesystem as Repository was moved out from UF and now it's part of Guvnor. Though I believe it would make sense to allow to set roles on FileSystem as well so access to it could be enforced.
