Support workhorse configuration and split workhorse to its own container
Closes #249 (closed)
I got somewhat spun around looking into adding these configs. I initially started working on the chart to have a good target for the image changes I was planning to make which would allow for additional command line args to workhorse. In the process I realized how straightforward it would be to both take steps toward #61 (closed) and add extraArgs by splitting workhorse and unicorn into separate containers (as mentioned in #50 (closed)). This has the added benefit of better logging and signal handling for workhorse too.
I've tested lfs uploads but I could still use some experienced eyes on things like env vars that probably aren't needed for both.
