CSI was previously using travis-ci for PR pre-submit testing and CI for this project. However travis-ci.org has been turned down and https://travis-ci.org/github/container-storage-interface/spec shows:

Since June 15th, 2021, the building on [travis-ci.org](http://www.travis-ci.org/) is ceased. Please use [travis-ci.com](http://www.travis-ci.com/) from now on.

We need a replacement pre-submit and CI solution. Opening this bug to track that work.
