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

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.
