This commits adds an E2E testing
to verify the metadata created by controller,
We are not checking the generated omap data,
but we will be verify PVC resize and binding
pvc to application.

In the case of Disaster Recovery failover, the
user expected to create the static PVC's. We have
planned not to go with the PVC name and namespace
for many reasons (as in kubernetes it's planned to
support PVC transfer to a new namespace with a
different name and with new features coming in
like data populator etc). For now, we are
planning to go with static PVC's to support
async mirroring.
During Async mirroring only the RBD images are
mirrored to the secondary site, and when the
user creates the static PVC's on the failover
we need to regenerate the omap data. The
volumeHandler in PV spec is an encoded string
which contains clusterID and poolID and image UUID,
The clusterID and poolID won't remain same on both
the clusters, for that cephcsi need to generate the
new volume handler and its to create a mapping
between new volume handler and old volume handler
with that whenever cephcsi gets csi requests it
check if the mapping exists it will pull the new
volume handler and continues other operations.
The new controller watches for the PVs created,
It checks if the omap exists if it doesn't it
will regenerate the entire omap data.

mirror deamon on the rbd image.

incase of async mirroring the volume UUID is
retrieved from the volume name, instead of cephcsi
generating a new UUID it should reserve the passed
UUID it will be useful when we support both metro DR
and async mirroring on a kubernetes clusters.

Docker Hub offers a way to pull official images without any project
prefix, like "docker.io/vault:latest". This does a redirect to the
images located under "docker.io/library".
By using the full qualified image name, a redirect gets removed while
pulling the images. This reduces the likelyhood of hittin Docker Hub
pull rate-limits.

An rbd image can have a maximum number of
snapshots defined by maxsnapshotsonimage
On the limit is reached the cephcsi will
start flattening the older snapshots and
returns the ABORT error message, The Request
comes after this as to wait till all the
images are flattened (this will increase the
PVC creation time. Instead of waiting till
the maximum snapshots on an RBD image, we can
have a soft limit, once the limit reached
cephcsi will start flattening the task to
break the chain. With this PVC creation time
will only be affected when the hard limit
(minsnapshotsonimage) reached.

Update the coding guide about MD014, i.e.
Dollar signs used before commands without showing output
Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
MD014 - Dollar signs used before commands without showing output
The dollar signs are unnecessary, it is easier to copy and paste and
less noisy if the dollar signs are omitted. Especially when the
command doesn't list the output, but if the command follows output
we can use `$ ` (dollar+space) mainly to differentiate between
command and its ouput.
scenario 1: when command doesn't follow output
```console
cd ~/work
```
scenario 2: when command follow output (use dollar+space)
```console
$ ls ~/work
file1 file2 dir1 dir2 ...

There is a type-check on BytesQuota after calling SubVolumeInfo() to see
if the value is supported. In case no quota is configured, the value
Infinite is returned. This can not be converted to an int64, so the
original code returned an error.
It seems that attaching/mounting sometimes fails with the following
error:
FailedMount: MountVolume.MountDevice failed for volume "pvc-0e8fdd18-873b-4420-bd27-fa6c02a49496" : rpc error: code = Internal desc = subvolume csi-vol-0d68d71a-1f5f-11eb-96d2-0242ac110012 has unsupported quota: infinite
By ignoring the quota of Infinite, and not setting a quota in the
Subvolume object, this problem should not happen again.

The implementation of getOMapValues assumed that the number of key-value
pairs assigned to the object would be close to the number of keys
being requested. When the number of keys on the object exceeded the
"listExcess" value the function would fail to read additional keys
even if they existed in the omap.
This change sets a large fixed "chunk size" value and keeps reading
key-value pairs as long as the callback gets called and increments
the numKeys counter.

The main() function of the cephcsi executable calls klog.Fatalln() to
report certain errors. This causes the executable to panic which is not
helpful to users that only need the error message.
By introducing logAndExit(), there is no need to call klog.Fatalln()
anymore.
