feat: Add otlp metrics exporter and update prom exporter

[AlexanderStocks]

Reason for Change:

This adds the otlp exporter with the environment variables required to configure strato, or any other generic grpc endpoint. This also updates the otel library which includes breaking changes to the Prometheus exporter

Requirements

• [ ] squashed commits
• [ ] included documentation
• [ ] added unit tests and e2e tests (if applicable).

Issue Fixed:

Fixes #1647 Does this change contain code from or inspired by another project?

• [x] Yes
• [ ] No

If "Yes," did you notify that project's maintainers and provide attribution? Its my code. Special Notes for Reviewers:
