* doc: update docs for volume options
There are around 340+ options. I have included the most used,
enabled by default, majorly affects the volumes or have been
facing issues recently. The 1st patch deals with prefix 'cluster.'
options. If I have missed any imp option please highlight or any
unnecessary options is added.
Owning to the huge list I move forward by creating a seperate md
file for vol options. More commits to follow. Just divided to make
review easy and quick.
