Introduce single container for rails webserver (Unicorn, Puma)
Combine Unicorn and Puma images into one, as gitlab-webservice
Selection of which web server to use is provided by GITLAB_WEBSERVER environment variable. If present, and set to a variation of puma, Puma will be used. Otherwise, Unicorn will be used.
This is based on top of the work from @dm3ch in !359 (closed). I rebased their work on the current master at the time, and then modified from there.
Relates to gitlab-org/charts&11 (closed)
