RBD Snapshot doc was the part of the README.md file. Hence,
renamed the cephfs-snap-clone.md file to snap-clone.md file
and moved the rbd snapshot document there.

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 ...
```

the older rbd images on the chain to avoid
issue in krbd.The limit is in krbd since it
only allocate 1 4KiB page to handle all the
snapshot ids for an image.
The max limit is 510 as per

added Hardlimit and Softlimit flags for cephcsi
arguments. When the Softlimit is reached cephcsi
will start a background task to flatten the rbd
image and return success and if the hardlimit
is reached it will start a background task
to flatten the rbd image and return ready
to use as false to make sure that the image
will not be used until it is flatten.
