Description of problem:
There currently is no way to specify a volume to be mounted when starting a docker container. This dramatically limits the usefulness of creating containers in Satellite (e.g. configuration files, persistent storage). For example, in order to run goferd in a container, you must mount /dev/log. As it stands there is no current way to do this with Satellite.

Version-Release number of selected component (if applicable):
Satellite 6.2.1

How reproducible:
Always

Steps to Reproduce:
1. Create a new docker container in UI, specifying a volume to be mounted.
2. Create a new docker container in hammer, specifying a volume to be mounted.

Actual results:
There is no way to specify a volume to be mounted.

Expected results:
You can specify at least one volume to be mounted, and option for multiples would be preferred.
