gNFS: Export / Netgroup authentication on Gluster NFS mount

* Parses linux style export file/netgroups file into a structure that
  can be lookedup.

* This parser turns each line into a structure called an "export
  directory". Each of these has a dictionary of hosts and netgroups
  which can be looked up during the mount authentication process.
  (See Change-Id Ic060aac and I7e6aa6bc)

* A string beginning withan '@' is treated as a netgroup and a string
  beginning without an @ is a host.
  (See Change-Id Ie04800d)

* This parser does not currently support all the options in the man page
  ('man exports'), but we can easily add them.
