Feature Request: Support for filtering versions

[akshaymankar]

We were trying to auto bump some of the software components that we use in our project. This seemed like the perfect resource to do that. But, we did not want to automatically bump major versions. It seems like the resource does not support filtering versions. I would ideally like to specify version filter like < 4.0.0 to specify that I do not want any 4.x.y version, but all releases to 3.x.y should trigger the pipeline.

I think this could be accomplished generically following concourse/concourse#1707 - you would configure a space filter like 3.*.
