Currently, the OpenShift-side of the web terminal story relies on the web terminal operator providing a default image to host the commandline utilities necessary (see https://github.com/redhat-developer/web-terminal-tooling/ / http://pkgs.devel.redhat.com/cgit/containers/web-terminal-tooling)

However, terminals' use and expectations are generally quite personalized for each user. To this end, it would be great to have an option, when creating a web terminal in the UI, to specify a custom/alternate image to use for the tooling container.

Examples include:

• An image that uses zsh by default
• An image built with your familiar `.bashrc`
• An image that has your desired tooling (vim, etc.)

The spec already supports this, so it would be as simple as updating the dockerfile template to optionally include a container component.
