this patch adds two new related features. first, it removes the
requirement that all monitor deployments be pinned to nodes using node
selector. this is allowed when not using host networking and when PVC
storage is used. the second feature introduced in this patch is the
elimination of the Rook scheduler for placing monitors that continue to
use the node selector by using canary pods to that are scheduled by k8s,
after which Rook uses the scheduling results to pin the monitors to
nodes.

This design proposes that rook creates and manages PDBs for all ceph
daemons. OSDs need special treatment and a new heuristic, but simple
PDBs will suffice for other daemon types.

This commit does multiple things:
* remove support for AllNodes where we would deploy one rgw per node on
all the nodes.
* a transition path is implemented in the code so that if someone has an
existing deployment, daemonsets will be removed and replaced by an
deployments.
* when using "instances", each rgw deployed has its own key which makes
Ceph reporting the exact number of rgw running, see:

The "Coexist with flex driver" section was overly technical about
details in the implementation of CSI vs. flex. Remove the detail
and replace it with more goal oriented paragraphs.

The user may want to connect to storage that is in a Ceph cluster,
independent from the local Kubernetes cluster. This design doc
describes the changes needed to enable the scenario.

this is needed as cryptsetup in the pod and udev on the host coordinate
via a semaphore that must be visible in both contexts.
note that additionally the host needs to have dmcrypt compiled with udev
synchronization, which at least one minikube version does not have.
