Simple tool to filter out lines from a go code coverage profile

Go Cov

Go cov is a simple tool to filter out results from the go test coverage profile. This usually means that we'll filter out generated files for which we don't want to write unit tests. However, we don't want these files to negatively impact our overall test coverage.

The rool reads a given coverage profile, filters out the lines that match the specified regulare expressions in the .coverage-ignore.yaml and writes the result back to the coverage report.
