Release 2020-06-22

Breaking:

- Logging system revamp:

  - Replace `bunyan` by `pino` as logger utility
  - Now log entries are written to stdout instead of a configurable file
  - Improved output of both analysis and errors for log entries to provide a better context

- Chore:

  - Minor changes in the tests to create the geomval type, if necessary, in the cdb_dataservices_client schema. This is done to match the behaviour of that extension.
