Remove multi-server controller

Removed all pages associated with the multi-server feature.
Before, this page was visible at /multi-server/overview.

This page is not used and there is a lot of work to get
multi-server working. There was also a lot of hardcoded values
in the multi-server controllers.

This code could still be used in the future by looking at the git
history or checking out an earlier tag.
Removing these controllers saves us a few KBs in the image.

Tested: Manual regression testing on a Witherspoon.
