Add support for taxonomies

[rizaardiyanto1412]

Can we add revisions support for taxonomies?

From user:

We're working on a new version of our knowledge base based on better docs.

It is essential for us to have a versioning and revision of posts and categories- they will be reviewed by someone before getting published. I know that posts support it. But I am looking for a solution to do it for the categories/taxonomies.
