Setup and configure logs

[dpordomingo]

As discussed we need to:

• [ ] Make sure, right log-level is used through the app.
  • Critical, when service went down,
  • Error, when the request could not be processed,
  • Warning, when the expected/normal behavior could not be followed but it was found an alternative,
  • Info, info useful when analyzing the trace of the process
  • Debugging, only for dev purposes
• [ ] Make sure the levels above are compliant with GCP https://console.cloud.google.com/logs/viewer
• [x] Make sure we can configure per deployment (environment) the log level
• [ ] Configure staging env to log >= Info
• [ ] Make sure there are no access logs (GET/PUT, etc) in the app logs on staging/prod envs
  • [ ] to do so, access logs should be logged with debug level

I saw many logs not following this issue desc. I have a local branch solving them. If you agree, I'll take care of this issue as soon as we have some time :D

Moving out of TODO as it seems not to have any progress and is not a critical bug
