This commit moves the mounting of a block volumes and filesystems
to a sub-file (already the case) or a sub-dir within the staging
path.
This enables using the staging path to store any additional data
regarding the mount. For example, this will be extended in the
future to store the fsid of the cluster, and maybe the pool name
to map unmap requests to the right image.
Also, this fixes the noted hack in the code, to determine in a
common manner if there is a mount on the passed in staging path.

Sometimes the tests fail cleaning up due unavailable resources that are
listed in the .yaml files. Deleting the missing resources returns
"resource not found". By passing --ignore-not-found to kubectl, this
problem should not happen anymore (and possibly makes it more obvious
where tests do go wrong).
rook master deploys the ceph-csi
by default now, this will affect the
ceph-csi testing failure, This PR will
remove the ceph-csi resources created rook

once we map the rbd image on a node
we will get the device name its mapped
in the map output itself,no need to
check the devicepath post rbd mapping

Use Deployment with leader election instead of StatefulSet
Deployment behaves better when a node gets disconnected
from the rest of the cluster - new provisioner leader
is elected in ~15 seconds, while it may take up to
5 minutes for StatefulSet to start a new replica.

It's CO responsibility to create the
stagingPath as per the CSI spec.
The CO SHALL ensure
// that the path is directory and that the process serving the
// request has `read` and `write` permission to that directory. The
// CO SHALL be responsible for creating the directory if it does not
// exist.

... and not that of the FS subvolume group `csi`.
There is no reason for setting the mode of FS subvolume group `csi`
(a CephFS subdirectory) as 777. It's default mode is 755. It's
sufficient to set the mode of FS subvolumes within the subvolume group
to `777`.

... instead of that of the `csi` subvolume group. The pool layout
specified via storage class's `pool` setting is a subvolume property
and not a subvolume group property. The `csi` subvolume group
may have subvolumes of different storage classes with different
pool layouts.

if mapping of rbd device is passed and mounting
device to stagingpath fails or if chmod on targetpath fails
,which may leave up stale mapping if
unstage is called
this will be fixed by unmapping if somthing fails

Every Ceph CLI that is invoked at present passes the key via the
--key option, and hence is exposed to key being displayed on
the host using a ps command or such means.
This commit addresses this issue by stashing the key in a tmp
file, which is again created on a tmpfs (or empty dir backed by
memory). Further using such tmp files as arguments to the --keyfile
option for every CLI that is invoked.
This prevents the key from being visible as part of the argument list
of the invoked program on the system.
Fixes: #318

Currently, provisioner creates user for every volume and nodeplugin
uses this user to mount that volume. But nodeplugin and provisioner
already have admin credentials, hence using the admin credentials
to mount the volume and getting rid of user creation for each volume.

in NodeStage RPC call we have to map the
device to the node plugin and make sure the
the device will be mounted to the global path
in nodeUnstage request unmount the device from
global path and unmap the device
if the volume mode is block we will be creating
a file inside a stageTargetPath and it will be
considered as the global path

Currently the cephfs PVC create/delete and all other operations
related to cephfs are failing. One of the recent commits in rook
900abbc967e108ad622648b740a7c57f1268209f has modified ceph-mgr
to run as ceph user rather than root user. The ceph user currently
has no permission to write to the root of the cephfs filesystem.
The fix will be external to CSI itself, but until that lands, sending
a workaround patch so the CSI CI is unblocked
In this patch, we are setting the permission 777 on root of the cephfs
filesystem. Thus ceph user will be able to modify the cephfs filesystem.
