Add Headless Container to each Gleaner run.

[valentinedwv]

Headless is a one 'summoner' at a time service. If more than one running gleaner accesses it, it can cause bad data.

So we need to create a single headless container Service with each run, or at least a container, that we start up and tear down since we don't need any configurations.

Needs to

• have a unique name that can be refered to as http://headless_RUN:9222
• a mount of /dev/shm to increase the size of shm mount.
• this is just needed for when a gleaner is running.
