implement something like node semantic-release in pipelines

[rawlingsj]

We have automated release pipelines on a lot of repos now which is great but we dont always need a release when say we make a readme update for example.

Node have something called https://github.com/semantic-release/semantic-release which uses commit messages to determine if an actual release is required + these also help generate nice release notes.

I wonder if we should implement something similar in the pipeline library?
