This adds the RemovePodsHavingTooManyRestarts strategy, added upstream in kubernetes-sigs/descheduler#254 and synced to our fork in openshift/descheduler#29.

This also updates the sample CR in the readme to show how to configure this strategy, and I made the change to now convert strategy parameter names to lowercase in our logic, allowing CamelCase params that are imo more readable.

I don't think that's really necessary, it's just one line (except for the Readme change) and functionally makes no difference to the existing behavior. But if it's easier for review I can if you'd like

There are other changes in README.md going from lower case to upper case. It's no big deal. It just makes clearer which change is adding the new strategy and which change is allowing the params names to be mix of lower and upper cases.

@ingvagabund the upstream PR has merged, so I updated this as well. Should be all good for a final pass
