Empty deployment list made the operator to crash as the condition check
was checking if the value at the 0th location is nill wich fails in case
of empty list. Updated it to check length of list not equals 0.

Example of failure scenarios:
- requested PVC 500M = 500,000,000 bytes
- PV is created as:
(500M / 2**20)Mi = "476"Mi
But 476Mi = 476 * 2**20 = 499122176 < 500M
From the k8s documentation:
Claims will remain unbound indefinitely if a matching volume does not
exist. Claims will be bound as matching volumes become available. For
example, a cluster provisioned with many 50Gi PVs would not match a
PVC requesting 100Gi. The PVC can be bound when a 100Gi PV is added
to the cluster.
which is inline with the behavior observed in which a 500M PVC is never
bound. However, the documentation also states:
If a PV was dynamically provisioned for a new PVC, the loop will
always bind that PV to the PVC. Otherwise, the user will always get
at least what they asked for
which suggests that an _explicit_ binding can be created, and perhaps
something has changed with respect to this binding that has caused the
failures in newer versions of k8s.

The beast fronted configuration for rgw is quite different than civetweb

This commit does:
* remove dead code SetCrushTunables()
* stop creating initial crushmap
There is no need to create an initial crushmap, since Ceph natively does
that for us.
We don't delete the existing configmap containing the initial crush map
of already deployed cluster, perhaps people are using for whatever
reason. It does not harm to keep it around.

Use cmd-reporter to detect Ceph version.
The job to detect Ceph version needs to run in a security account context
capable of getting/creating ConfigMaps, so a new security account, role,
and role binding are created for the cmd-runner jobs. In the future, the
Ceph mgr may create jobs in this service account for running
`ceph-volume` on nodes, and this also keeps Rook operators controlling
multiple Ceph clusters independent.

Add a wrapper for the cmd-reporter function of the 'rook' binary to
k8sutil so that it's easier for operators to use the functionality.
Operators still need to have some idea of how CmdReporter works. It runs
the requested command in a job, but if the calling operator needs the
job to have special configuration, the operator must request the pointer
to the job struct from CmdReporter to modify it before calling the
CmdReporter's Run method.

If we are running a Ceph cluster that has an unsupported version and if
we have set allowUnsupported: false, a newly bootstrap operator will
fail to start. To fix this, the user will update the CR and set
allowUnsupported: true, however at this point clusterInfo hasn't been
initialized so the operator will panic because we were referencing a nil
pointer.
To fix this, we re-populate clusterInfo if necessary and things go
smoothly.

Somehow during startup the arg got misinterpreted by ceph-osd and was
failing with:

This change is meant to allow running operators locally on a developer machine.
The idea is to allow faster development cycles by reducing the time and complexity of building -> deploying -> debugging on cluster.
For operators that rely only on kubernetes API this works easily - see cockroachdb and minio examples in development-flow doc.
The change includes:
- rook.NewContext() - Refactored to remove repeating initialization code that was copy-pasted in most of the operators in order to create the clusterd.Context and the Clientsets. Also it detects the mode of working in-cluster vs external and sets up the external mode with standard user config (~/.kube/config) and a job executor.
- rook.GetOperatorImage() - Refactor this repeating code in many operators to detect the operator pod image. Also added a global flag --operator-image that developers can use to override this when running locally.
- rook.TerminateOnError() - Added a convenient function.
When the operator first starts, the only operation needed
is to watch for new cephcluster crds to be created and
start the discovery to find available devices. The flexvolume
agent, the csi driver, and the volume provisioning can all be delayed
starting until the first cluster is created.

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:
