Enable Telemetry Job to configure an endpoint for the exporter

[shaun-nx]

As an engineer, I would like to have the option to configure the OTEL endpoint that telemetry data will be sent to.

### Tasks
- [x] Add CLI argument for configuration
- [x] Update collector to use [telemetry-exporter](https://github.com/nginxinc/telemetry-exporter)
