[TEST] #2 Adding nfs_netfs_setup() to configure nfs server setup...
Updates:
--------
Patch 2:
--------
1) Removed the mount command
2) Rearranged the nfs_config steps to check the nfs bin existence first
3) Added code to backup the original /etc/exports file
4) Modified netfs_cleanup to restore the backed up /etc/exports
Patch 1:
--------
1) nfs_netfs_setup() configures the nfs server and makes necessary arrangements for
netfs pool creation.
2) nfs_config() setups nfs server
3) netfs_config() makes necessary arrangements for netfs pool creation.
4) get_nfs_bin() gets proper nfs server binary
5) clean_temp_files() cleans the temp dir created for nfs mount
6) netfs_cleanup() cleans up removes the dir created, restarts the nfs server..
Tested on F10 with KVM and current sources.

[TEST] #2 Adding netfs diskpool creation to RPCS/08_CreateDiskResourcePool.py tc..
Updates:
--------
Patch 2:
--------
1) updated the tc to verify if the support for dir and netfs support pool creation
exist in the providers.
2) Updated the test to verify if Libvirt version on machine has capability to support
storage pool.
Tested on F10 with KVM, Xen with current sources.
