Create kubernetes probes #47
Description
At the beginning of the Operator project I didn't really find a reason to create probes for the operator -- e.g. readiness probes and/or liveness probes. But now, since much effort is going to be done to improve the operator and move away from some component of kube-builder and operators in general, I am thinking of creating probes to the operator.
For example, since the operator will not have dependencies on mounted files, the operator will be able to to start even without any settings or secrets deployed to kubernetes and it will not crash (what it does now), but will merely wait for it to happen, sending not ready values to the probes. This will make the operator more flexible as it will wait for users to deploy the needed file and this does happen the probe will receive a ready state. The normal behavior will occur, which is that after x consecutive not ready values, the operator will be restarted, which currently happens immediately right now.
There are many other use cases, which I will show when this is implemented.
