Oak run check command must return the status of repository consistency check

Currently the consistency check reports only if the command runs successfully (return code 0) or fails (return code 1).
Into this logic will also add the status of repository consistency:

• checking only the last revision: will return 0 if the revision is consistent and the command runs successfully OR will return 1 if the revision is inconsistent or job did not run successfully (some errors/exception were encountered during the run)
• checking multiple revisions: will return 0 if at least one revision is consistent and the job runs successfully OR will return 1 if none of the revisions are consistent or the command did not run successfully (some errors/exception were encounter during the run)
