Add a prefix to the csi drivername when ceph csi is deployed by rook.
This aims to prevent trivial conflict between csi instances when two
rook operators are deployed into the same cluster. By default the
prefix is the "<rook-namespace>." but can by customized on the cli
and via environment vars.

Avoid using global values that are not used anywhere in the code.
Split the object used to express the ceph csi templates into two
so only values that are set globally need to be managed globally,
all other values can be stored in the temporary local struct.

Instead of requring csi instances for every ceph cluster that rook
manages, maintain one config map for all ceph clusters. This allows
for one set of csi drivers per rook operator.
The config is intialized as empty when Ceph CSI components are first
created and then updated every time a cluster's mons change.
As before clusters are identified by the k8s namespace the ceph cluster
is running in.

Thes values being defaulted "on" cause issues with some of the units
tests but add no additional value to the normal rook ceph binaries
because they are immediately overwritten by the values set on the
command line (and env).

The flex driver does not need to be started if
only the CSI drivers are going to be used. Therefore,
we allow the admin to stop launching the rook flex
agent with the setting ROOK_ENABLE_FLEX_DRIVER in
operator.yaml

CSI is now the preferred storage driver for Rook.
By default both the CSI and flex drivers will be started
by the operator. In a future release the flex driver
will be deprecated, but for now is still supported.
The drivers can be disabled with an environment
variable in the operator deployment in operator.yaml.
If users are only using one driver or the other there is
no need to enable both drivers.
