### Changes

* New command line argument --jiraIds or -j

If this argument is given, its expected your executing jobrunner from a directory that is a local git repository

If jira ids are found, it will both include BUILD_JIRA_IDS environment build variable to a given job, but it will
also assign BUILD_JIRA_IDS to an environment variable.

This allows for bitrise jobs to call jobrunner with argument and get jira ids for slack commands, since bitrise
would have already had the repository cloned.
