"updates_available" feature floods PackageKit with requests

[Tal Liron]

This feature, enabled by default on many operating system configurations, calls "pkcon get-updates" every second. This is a heavy call that uses quite a bit of CPU and also floods journald with logs.

The exact place this happens is here:

https://github.com/dustinkirkland/byobu/blob/master/usr/lib/byobu/updates_available#L59

The recommendation of the PackageKit maintainer is:

"The smart way is do GetUpdates on coldplug and then watch for the UpdatesChanged signal."

This was actually quite hard to debug! I originally opened an issue for this on PackageKit, which eventually led me to Byobu. You can see the maintainer's response and whole thread here:
