Add bumpver configuration

This is directly called from ops/deploy, so usage of this tool is
abstracted and not super important.

It's easy to use however, and has a string input method, instead of
incrementing each part individually, a la bump2version.

```

INFO    - fetching tags from remote (to turn off use: -n / --no-fetch)
