KCI nightly build schedule

[Rik Mills]

Currently this it set to run at midnight UTC seven days per week.

On Sunday morning LP undergoes some scheduled maintenance, meaning for a
period of 4 hrs or more the LP publisher does not run, so builds appear
to fail with a time-out.

Coupled with the facts that some of our contributors in non European
time zones find that the nightly at the weekend clashes with times when
they may be able to work on packaging fixes, and that the traffic of
upstream git commits by KDE dev is very much slower at the weekend, then
it has been suggested that at least the build at 0:00 UTC Sat
night/Sunday morning may be worth dropping. There is also a case for
arguing that we just set the schedule as Mon-Fri and be done with it.

This would have the benefit that contributors with spare time at the
weekend could get stuck into fixing things without the nightly build
blocking or delaying builds triggered by their packaging changes.

Obviously the nightly could be manually started if it is clear no-one is
doing much.

Opinions on the above gratefully received.
