All tests that were failing in CI with this diffs showing traces with
context, which correspond to a default `VERBOSITY verbose` in the server.
Since we migrated the CI to postgres 9.6 it makes sense to see such
differences in server configuration.
Enforcing the verbosity level makes the tests more robust indeed.
Add routing with waypoints functions to client and server. Includes
signature checks tests for the Postgresql functions and unit and
integration tests for the Python library.
Add client v0.6.0 and server v0.9.0
