The pg_autoscaler is always enabled by ceph and cannot be disabled.
In a previous PR the pg_autoscaler config was removed from the main example.
Now the remaining config for the pg_autoscaler is removed as well.

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.

To make it easier for the user to switch to a namespace other than the
default 'rook-ceph', the tag '# namespace:cluster' must be inserted in
all the places where this namespace is used. This way, a simple 'sed'
command can update all the Yaml files to the new namespace.

The machine disruption budgets for handling openshift
machines and machinesets are now removed since they
have been unused and unmaintained since implemented.
This feature is expected to be handled with the more
common Pod Disruption Budgets. A workaround is for the
cluster admin to set up their machine sets so they
match the zone topology. See the original design
doc from the feature here:

For the Rook v1.10 release we want the latest version of Quincy to

By default, we should set the priority class to one of the built-in
priority class names to ensure that pods critical to the storage
will be able to remain running when resources are low. Otherwise,
critical rook pods could be evicted and affect many other pods
that rely on the storage to continue functioning. The options have
been available in the CRs, but until now we have just not set the
defaults in the examples. Critical rook components are now set to
the priority class system-node-critical if they are generally pinned
to a node, and system-cluster-critical if they are critical to the storage.
Some pods such as the operator and crash collector do not have a
default priority class set in the examples since they don't affect
the data path.
