Automate releases to clojars from release tags

[k13gomez]

I'm working on a small PR to automate clojars releases from release tags, release process would be the same as right now (but automated), see steps below:

1. prepare for release by updating changelog and updating release version, commit to main branch.
2. create tag to match release version, push tag.
3. build runs for release tag and gets automatically deployed to clojars.
4. prepare for development by updating snapshot version, commit to main branch.

After merging 474 and creating a tag the automated deploy was not triggered (I had to do a manual deploy), I suspect something wrong with the regex pattern, so I will open another PR when I have a chance to test this on a test repository.

I suppose the auto created tag will need removed?

The tag is still created manually, that part is fine, and since the deploy job did not trigger (but I still wanted to release 0.21.2) I did a manual push; just the auto deploy needs more work, further changes will be needed in the travis config file.

I opened a corresponding PR for the 0.21.2 release docs here: oracle-samples/clara-site#40

I've opened a new PR which should address the problems with the deploy step.
