Refdiff to support another set of parameters tag regex and tag limit, and calculate diffs based on these 2 parameters

[klesh]

Description

Refdiff currently accept only pairs and calculate diffs for them, this is not very flexible, because most of the time, user would like to know diffs of latest releases. It's no point to calculate same set of pairs over and over again, especially with pipelines that triggered by blueprint

Describe the solution you'd like

Beside pairs, refdiff can accept tagsPattern and tagsLimit, maybe evens tagsOrder(alphabetically , semver). and refdiff would filter tags by these parameters, sort them, take last tagsLimit tags, and calculates diffs for them.

Has the Feature been Requested Before?
