The GitHub credentials section now allows setting some API endpoints
that point the github client and the runner setup script to the propper
URLs. This allows us to use garm with an on-prem github enterprise server.

Runners can now be manually removed using the CLI. Some restrictions apply:
* A runner must be idle in github. Github will not allow us to remove a runner
that is running a workflow.
* The runner status must be "running"
