Feature Request: Option to delete old successful runs.

[mk-pmb]

Hi! This looks rather promising. However, I cannot find the option I want: To also delete successful runs that are older than x days, accepting fractions (0.5 = 12 hours). Could you add that, please?

Edit: In case anyone else needs a stopgap sooner, I made one.

💡Good idea. Will add another additional flag remove-older-than.

Opened #37. For now only proposed API addition – open for suggestions

This feature should support time period or number of builds to keep.
