mod_http_file_share: Improve consistency of terminology in logging Prefer 'prune' over 'delete' since it more strongly implies removal of excess.

mod_http_file_share: Rename variable for clarity

mod_http_file_share: Fix deletion counter Before aa60f4353001 each loop had its own counter, seems incrementing of one of them was lost. But only one is needed anyhow.

mod_http_file_share: Back out 876e1b6d6ae4

mod_http_file_share: Recalculate total storage usage weekly instead of daily Before mod_cron this job ran less frequently than the upload removal job. Running them at the same frequency seems wasteful somehow, plus the total should not drift away from the true value that fast.

mod_cron: Add a 'weekly' job frequency

mod_cron: Initialize timestamp of new tasks to start of period Makes it more generic so new periods (e.g. weekly etc) can be added easily.

mod_cron: Follow convention of imports at the top

mod_http_file_share: Keep track of total storage use across restarts The value needs to be known in order to determine if additional uploads can be accepted.

mod_http_file_share: Fix measuring total storage use before it was known Passing nil to the metrics system causes errors later.
