Ramana Raja a8e522961c ganesha: dynamically update access of share
You can dynamically update access lists of exports with Ganesha
version >= 2.4. Make ganesha library use this feature in a new helper
class, GaneshaNASHelper2, to cleanly implement share access rules
changes without undesired interruptions.

When updating a share's access rules, the new helper class differs
from the older GaneshaNASHelper class as follows:
* Looks for an existing export and edits its client access list;
  creates a new export if it can't find one; and removes an export if
  the access list ends up empty. Rather than awkwardly create or
  remove an export per addition or removal of an access rule.
* Issues DBUS UpdateAccess command to dynamically update an export.

features:
- The new class `ganesha.GaneshaNASHelper2` in the ganesha library uses
dynamic update of export feature of NFS-Ganesha versions v2.4 or newer
to modify access rules of a share in a clean way. It modifies exports
created per share rather than per share access rule (as with
`ganesha.GaneshaNASHelper`) that introduced limitations and unintuitive
end user experience.
