Removing Travis CI completely in favor of local vagrant/virtualbox tests.

See tests/pararlell.sh and tests/Vagrantfile for local tests.

There are several reasons for this change:

1. Travis is now charging for the service, even for open source projects, contrary to what they promised in the past
2. It has been problematic and difficult to debug/diagnose issues
3. Tests that involve upgrading the operating system itself (eg. Bionic to Focal) are not possible
