Migrate CI from Travis to GitHub Actions

Added reporting of test results via the testbox junit reporter

6.0 https://github.com/lucee/Lucee/pull/1371

5.3 https://github.com/lucee/Lucee/pull/1372

@Justin Carter I got the build trigger working, but it’s returning
Could not authorize build request for lucee/lucee-dockerfiles.

https://travis-ci.com/github/lucee/lucee-dockerfiles/requests

https://github.com/lucee/Lucee/runs/2904898911?check_suite_focus=true#step:16:10

I have disabled concurrent builds with GHA, any new workflow run cancels the current workflow run, they can manually be triggered. At the moment this is global across all branches.

Once the s3 tests are improved we can make this per branch & (push or pull)

for docker builds (5.3 and 6.0 branch)

tho 6 isn’t setup up yet to build (not ready)

https://github.com/lucee/Lucee/commit/0c2fdf1569a150e60569f308f7400b95c2b7e80e

5.3 now builds, passes and publishes to s3, 5.3.8.187-SNAPSHOT is out

I have also added build and test for most major extensions, which run labelled tests against the 6.0 branch using 6.0.0.95 snapshot

I have created a GitHub action to run Lucee to do this

For example,

here is the mysql GHA https://github.com/lucee/extension-jdbc-mysql/blob/master/.github/workflows/main.yml

here is the lucee docs GHA https://github.com/lucee/lucee-docs/blob/master/.github/workflows/main.yml
