Harmonize output of cron-tasks.
refresh_keys
and check_keys
currently produce differently styled output.
E.g.:
Key DEADBEEF... was updated (new signatures)
vs.
Expires in 5 days:
0xDEADBEEF... <bla@foo>.
This MR proposes to harmonize the output using the first style, so that the latter example would read:
Key DEADBEEF... expires in 5 days.
If someone would like to argue for a different text-style now would be a good time to do it.
