Add tools to better manage git-annex remotes and DDR inventory

[gjost]

We discovered that git annex special remotes for backing up our binary files were not as up-to-date as we thought. This was due to a lack of data about the status of DR collection repositories and their remotes, which led to a breakdown of manual backup processes.

• [x] Add CLI command ddrremote check
• [x] ddrremote check write script info to log e.g. YYYY-MM-DDTHH:MM:SS ddrremote check ERROR missing hq-backup-gold files/ddr-pc-32-1/files/ddr-pc-32-1-administrative-bd7710419c-a.jpg
• [ ] mod script to skip repos checked recently(?) checked since DATE(?)
• [x] --mod-script-to-sleep-1-2min-betw-collections-- (NOPE this happens in calling script)
• [ ] ddrremote recap DAYS command to report what repos were modified within DAYS, focusing on repo creation and addition of annex files.

I ended up adding the following:

ddrremote copy

Wrapper around the git annex copy command that works with both rsync and b2 remotes, and which logs metadata about the copy operations.

ddrinventory report

Gathers data from local repositories, Cgit on mits2, and specified git annes special remotes to report the state of various parts of the Repository.

• Presence or absence of repositories in the local filesystem.
• Sync status of local collection repositories' status compared to Cgit.
• For each special remote:
• Presence or absence of collections' data in remote.
• Presence of files added since the last git annex copy.
• Errors or inconsistencies in the data from copy operations.

We have a good-enough solution for the time being. Revisit later for something better...
