Create proxy and websocket configuration configmap for wrongsecrets-balancer

[commjoen]

Given we will have to upgrade the webtop often, we need to be able to easily adjust the requierd proxying in the wrongsecrets-balancer. That is why we need a configmap that contains a mapping for:

• which urls should end up to a websocket upgrade to which service
• which urls need to be proxied to which address

so, something like:

• websocket
  • servicename1:8080:
    incomingurl1
    incomingurl2
    incomingurl3
  • serviname2:3000
    incomingurl4
    incomingurl5
• proxy
  • servicename1:8080:
    incomingurl6
    incomingurl7
  • servicename2:3000
    incomingurl8withwildcard
  • servicename3(CTFD)
    incomingurl9
    incomingurl10
  • servicename4(grafana)
    incomingurl10

the deployment should mount the configmap in so that the balancer its code should be able to read it. both the deployment and balancer code need to be adjusted.
