50f8d72408 adjust timeout / retry timing 
resolver timeout 5 -> 10s (so it has more chances to query both nameservers alternatingly)

unavailable retry 300 -> 120s (so in case of a temporary problem, the outage is shorter)

6261b64b72 catch more query_ns exceptions. try update/delete even if query_ns failed. 
it could be maybe the secondary DNS that failed for query_ns, so we can still try talking to the primary.

c432e24c0d add a managment command "domains" to check the domains, notify owner of domain, update admin docs 
if a nameserver is not reachable or does not answer queries for the domain, the domain is flagged as not available (and also as not public).

also added catching of PeerBadKey exception.

57641f3b9a allow single-host update secrets, make dnstools tests work for everybody 
the nsupdate.info zone is configured to allow updating test.nsupdate.info with a non-secret key used for the tests.
we also have a test that tries to update another host with that key and checks that this fails.

change the tests so they only use test.nsupdate.info (if possible).

single-host update secrets need a Domain record for the fqdn of this single host, the fqdn is tried first, before it tries the origin zone.

6bf1f57fc1 deal with not responding nameservers (offline or unreachable) 
if a nameserver does not respond, we flag it in the database
(available = False) and stop talking to it for 5 minutes.

after 5 minutes, we flag it available = True again and retry talking to it
(and if not successful, flag it as unavailable again).

this avoids a unresponsive UI as we do a lot of ns queries from the templates
to get v4 and v6 addresses of our hosts from master nameservers.

we log a warning when setting unavailable and a info when setting available.

d558e2ece2 store update_secret as salted sha1 (use crypto code from django), fix bug: we also need to catch NoAnswer, not just NXDOMAIN. 
NoAnswer == there is a record, but not of the type (A or AAAA) we requested.
NXDOMAIN == there is no record at all.
