Add date filter

[tpak]

Describe the feature or problem you’d like to solve

I would like to see all cache's created before or after a certain date.

Proposed solution

add a flag such as:

--age <string> Return caches older than age (1m/2m/1d/2d/xd/1h/6h/xh)

Where the number of months/days/hours is variable and there are options for month/day/hours of age (perhaps minutes)

Additional context

It would benefit users so that we can list old caches and then delete them in a script or understand which branch or branches are aging. This could be combined with a bulk delete operation, as discussed in #20 but would also be useful on the list and delete command.

As I have been configuring cache cleanup jobs, I would like to clean up only caches older than a certain number of days/hours so that branches with high current activity levels do not have their caches deleted unnecessarily. This requires unnecessarily complex pipes to external utilities such as awk/grep etc.

We currently get this type of answer back and need to parse that and cut it down - sometimes it says minutes, hours, or days making it awkward to write a simple script.
