v1.4.1 fixes the default exporter ref not pointing to the latest release.

It also includes some minor docs changes.

The most notable change in this release is a stability fix:

Previously, the helm charts pointed the exporters to master.
That meant if you checked out a tagged, stable release, you'd still be pointed
at the unstable master branch for the exporters.
Now, the exporters will point to the latest stable tag by default.
If you currently have `source_ref: master` in any of your exporters but you want to
use a stable version, you can just delete that key.

You can also now filter the projects searched for in the Jira failure-exporter
with the environment variable `PROJECTS` (see https://github.com/konveyor/pelorus/pull/308
and the docs at https://pelorus.readthedocs.io/en/latest/Configuration/)

Finally, the images used for exporters no longer depend on having entitlements.

The remaining changes are more behind-the-scenes--
cleaning things up and improving testing so we can develop fearlessly.

Happy coding, and may the pelorus guide your way.
