[PATCH] pynfs: add courteous server tests

[Calum Mackay <calum.mackay@oracle.com>]

Add a first test that simply locks, sleeps for twice the lease period,
then unlocks.

I plan to add some more tests shortly, but will send what I have now,
in case it's useful for the upcoming BAT. This first test has been tried
against Solaris & Linux (discourteous) servers.
