Adding opentelemetry

[bitbyt3r]

This adds opentelemetry support to ubersystem.

Config:

[otel]
enabled = True
endpoint = http://signoz-otel-collector:4318/v1
sample_rate = 50 # Only log 50% of the requests
tools.otel_request_attrs.on = True
tools.otel_metrics.on = True
tools.otel_reset.on = True
server_name = super2024

This requires line of sight to an opentelemetry collector server. When enabled, it pushes:

• Logs
• HTTP Request traces which contain:
  • DB Requests
  • Outgoing HTTP requests made with the requests library
  • Jinja template compile/render
  • View functions
• Metrics (Currently not many. #db queries, #rows returned, page render time)
• Exceptions

All of the above are corollated with each other, so you can dig into any web request and see the logs, exceptions, DB queries, etc that it made.

Looks good to me!

Since we're putting defaults in the configspec file, do we need this set of hardcoded defaults?

Should we pin these libraries? I'd hate to get a broken build because our telemetry library had a breaking change.
