Enable cron in Dom0

[joanna]

Currently we expect to use cron for the qubes-dom0-updates.cron, yet we don't have it running in Dom0. We should probably add it to the requirements list of qubes-core-dom0. Unless we don't want to use it for some other reason?

Also, if we decided to use cron in Dom0, then we might want to rewrite keep-dom0-cloc-synced into a cron job.

This decision was already made. Especially here is (incomplete) implementation: ​http://git.qubes-os.org/gitweb/?p=marmarek/installer.git;a=commit;h=50caa8513fdfb5fd484de9086927dd39ac858f8f.

BTW now dom0 clock is synced every resume - perhaps it is enough?

Wouldn't it be more logical to add cron to the requirement's list of core-dom0, instead of manually editing comps list? Some time later, some person, might conclude that cron is usless in Dom0 and remove it from the comps list, when doing some "cleanups"...

Also, dom0 clock should also be synced by cron and not only by suspen/resume -- we can think of users who don't suspend the machine for long period of times, and we don't want their clocks to get desynced...

Also cron added to qubes-core-dom0 requires:
