Format RBD volumes with nodiscard formatting options.

Browse Source 
Currently rbd CSI plugin uses formatAndMount of
mount.SafeFormatAndMount. This does not allow to pass or use
specific formatting arguments with it. This patch introduce
RBD specific formatting options with both xfs and ext4,
for example: -E no-discard with ext4 and -k option with
XFS to boost formatting performance of RBD device.
