feat: add otel operator and sample configurations

[qdzlug]

Proposed changes

This is the first step at integrating the observability changes into the project. This deploys the OTEL operator into its own namespace, and then instantiates a collector in the observability namespace.

The configuration for the collector is kept intentionally simple; by default the collector will listen for OTEL traffic on grpc and HTTP, and output that data to the stdout of the container. The output is summarized.

For additional configurations, please see the README in the observability directory.
