When CPU requests and limits are assigned to a pod,
the pod will be guaranteed the requests, up to the limits.
Even if there are spare CPU cycles, the pod cannot use
them. Thus, pods can be unnecessarily denied compute
when they need to burst if the limits are set.
Therefore, it is not recommended to set CPU limits
since the CPU requests are already guaranteeing that
no pod will be starved at least for its requests.

Based on the latest info from the Ceph RGW team, update all probes. Get
rid of the liveness probe entirely. Update startup and readiness probes
to support return codes for misconfiguration (500) and for server-side
throttling (498 or 503).

Remove the health checker for CephObjectStore. The liveness and
readiness probes go through the same code paths in RGW as creating
buckets without as much affect on the storage backend.
