GitLab

+ move all schemas into formats
+ add test messages for semver, commit ref and branch

Only reload remote refs if absent or on request
This avoids the runtime resolving the live refs on startup

This allows us to include Feature and FeatureCollection
We probably don't need FeatureCollection for now at least
We do need Feature since the primitive list will
contain a list of features of varied geometries

- revert changes to emergency schema
- remove Feature and FeatureCollection

- use discover to find python unittests
- choose filename for output compiled schema
- use python+node container for JS tests
- compile ignored test schema before running all tests

This is a workaround until a new version of Flasgger
is released.

feat: dockerised and composed everything up, introduced run-compose and gitlab-ci
