Enable new mirrorlist server on proxy14

After a successful test of the new mirrorlist server code in staging,
this is the next step. Try to make it work in production on one of the
proxies. As discussed on the mailing list we are trying the new setup
with proxy14.

All the conditionals have been updated to be 'staging or proxy14' and
the mirrorlist data generation has been enhanced to also write out the
new protobuf based format on the backend system.

At the same time this moves the pickle/protobuf generation from :55 to
:30 as this generation takes much longer than it used to be and the
mirrorlist server restarted at :15 was never using the new data during
the last few months.
