[OTDev] A&A: Policy cleanup

Hi all,

about 50% of the currently registered policies (~5200) are not FQDNs.
Therefore, according to today's discussion, i propose the following:

I will run an initial policy cleanup this night, starting from 10pm CET.
This will then be repeated in weekly intervals, starting on Monday, Feb 
7 2011, 10pm.
Monday is chosen to allow running test installations over the weekend.

A cleanup will remove all policies associated with non-reachable URIs,
A URI is considered non-reachable, if the hostname does not resolve via 
nslookup.
As a means to cut down on network traffic, cleanup will delete in a 
first sweep all hostnames without a top-level domain and try DNS lookup 
for the rest.

Best regards
Andreas
