Add support for zfs mount -R <filesystem>
This commit adds support for mounting a dataset along with all of it's children with '-R' flag for zfs mount. There can be scenarios where we want to mount all datasets under one hierarchy instead of mounting all datasets present on system with '-a' flag. '-R' flag should work on all root and non-root datasets. Usage information and man page has been updated for zfs mount. A test for verifying the behavior for '-R' flag is also added.

# DESCRIPTION:
|

# Verify zfs mount -R <filesystems/s> functionality.
|
||||
#
|
||||
# STRATEGY:
|
||||
# 1. Create nested datasets
|
||||
# 2. Unmount all datasets
|
||||
# 3. Recusrively mount root datasets, this should mount all datasets
|
||||
# present in a pool
|
||||
# 4. Unmount all datasets
|
||||
# 5. Recusrsively mount child datasets with children. This should mount
|
||||
# child datasets, but not the root dataset or parent datasets
|
||||
# 6. Unmount all datasets
|
||||
# 7. Mount root dataset recursively again and confirm all child
|
||||
# datasets are mounted.
