This is for advanced use-cases only, and should generally not be used.
However, adding volumes is not possible from parent helm charts, so this is a limited, but useful, extension point.
I need to support an in-house acl solution for hubot. We use a hubot script to provide that feature. Given the current chart, there is no clean way to inject these scripts before chatops is started. This PR adds a simple, targeted way to enable this feature while keeping its footprint small.
NB. In my case, I have a custom docker image that includes the dependencies for my script, but there is also a config file that needs to be deployed via a volume of some kind, so embedding that in the docker image as well isn't feasible.
