Currently XWD has the option of k8s-mwdebug, which directs traffic to mwdebug.discovery.wmnet. We should extend this, and add the option to choose between mwdebug in eqiad and codfw, so to allow us to run ab tests between then two, if we need to.
suggested options are:
- k8s-mwdebug-eqiad -> mwdebug.svc.eqiad.wmnet
- k8s-mwdebug-codfw -> mwdebug.svc.codfw.wmnet
