[BUG]Openshift - cc does not delete objects it created

[nmenant]

Description

<For bug: Describe the bug in detail, observed versus expected behavior, steps to reproduce the issue, and a brief description of your deployment scenario>

When we use CC to handle Openshift routes, it will create all the needed objects on BIG-IP. However if we delete these routes, some objects will be deleted while some others will remain. It may be good to make sure that CC handle the whole lifecycle on any objects it creates on the BIG-IP

Example of objects that cc will not remove when a configmap / route / ab deployment is deleted:

• if there is no more route, we would expect that the default http/https vs would be deleted
• nodes will remain
• the iRule to spread the traffic between two application in an ab deployment remains. Its related datagroup remains also
• http_redirect_irule remains
• openshift_passthrough_irule remains
• https_redirect_dg datagroup
• ssl_passthrough_servername_dg datagroup
• ssl_reencrypt_servername_dg datagroup
• ssl_reencrypt_serverssl_dg datagroup
• Any monitors created through routes setup

Here is an example of my /config/partitions/kubernetes/bigip.conf after deployed a confimap, routes, ab deployment and then deleted those items. It would be expected that it's empty.

A few notes of things I've noticed:

• iRules and datagroups are currently long lived. They are created on startup and only have purpose if Routes (or Ingresses for redirect) have been created to use them, otherwise they are stale.
• If multiple Routes w/ monitors are created, and one Route goes away, its monitor remains.
• If all Routes are deleted, all resources are cleaned up (except iRules/datagroups)

yeah, i've tested further and that's what i've seen. I was monitoring all the namespaces by default with CC and therefore i had additional pools that got created (like for docker registry). Therefore all the monitors remained as highlighted by @sjberman .

I've changed my cc setup to only monitor my demo namespace and now everything is deleted properly with the exception of iRules Datagroups when all my routes are deleted
