Address Docker issues and remove need to extract cdclient.fdb (#895)
* Implement a server res directory

* Only convert if neither exist

* Remove unzip, Update RegEx

* readme updates

Run setup after setting working dir

Address several docker issues

Revert "Run setup after setting working dir"

This reverts commit fd2fb9228e82a350204c1ef61f7ba059479bb12f.

Fix docker

* Remove extra submodules

* Rework logic

* Switch if block
