* Add GitHub Action workflow for tests
* Add workflow to check formatting
* Remove travis-ci config
* Fix clang-format error
* Add shared json extension for tests
* Hide output for xfail tests
* Use mongo-orchestration configs from drivers-evergreen-tools
* Drop obsolete test scripts
This drops the legacy VM environment and remnants of the travis-ci config
* Remove obsolete server_id config
* Add note about MONGO_ORCHESTRATION_URI to contribution docs
* Restore previous XFAIL behaviour
This did not have the expected effect of preventing diff output for tests that expect failures, so it can be reverted.
* Make SSL certificate path configurable for tests
Since mongo-orchestration will always bring its own certificates, we need to set the correct SSL certificate directory for our tests. This is skipped on GitHub Actions as we don't test SSL builds there (yet). If SSL_DIR was not set, tests requiring SSL will be skipped.
* Fix code review nits
