Determine where the UID that's appended to Jenkins slave names comes from

[robled]

If the Ansible variable jslave_name is set to something like 'cinch-slave', when the Jenkins slave is created it will had a UID of sorts appending to the end of the name, like 'cinch-slave-123fdsa'. We need to find out where this is coming from, and possibly make its existence user-configurable.

Not to resurrect this from the dead, but I believe the appended ID comes from the java swarm client call.
According to the docs you can pass a -disableClientsUniqueId to disable that feature.

An example of where this gets set is the swarm service template, seen here: https://github.com/RedHatQE/cinch/blob/master/cinch/roles/jenkins_slave/templates/swarm.service#L17. However users can already disable this feature but overriding the ansible variable "jswarm_extra_args", which is set by default here:

cinch/cinch/roles/jenkins_slave/defaults/main.yml

Line 12 in 3dfaf60

jswarm_extra_args: ''

Overall this can probably be closed as won't fix. Alternatively, a doc update could address this if this is a FAQ.
