[cmd/opampsupervisor] Add configurable telemetry options for supervisor

Is your feature request related to a problem? Please describe.

Currently monitoring the supervisor consists of capturing debug level logs from stdout. Soon there will be limited configurable logging options (see Additional Context) but there's no support for metrics or tracing or advanced logging options. As it matures, the supervisor should support more monitoring capabilities allowing any emitted telemetry to be captured.

Describe the solution you'd like

Something similar to the collector's service.telemetry configuration options could solve this problem. Granted it is not stable so there's room for change, but consistency between the collector and supervisor would be ideal. The service.telemetry config can be found here.

Describe alternatives you've considered

The supervisor could recognize the TelemetryConnectionSettings OpAMP message that is sent to the collector and send it's own telemetry to the specified destinations as well. However this would need more consideration to determine viability, especially since the supervisor currently doesn't forward this message to the collector for configuring collector telemetry.

Additional context

I have a PR open at the moment that lays the ground work for adding telemetry configuration starting with logs and the ability to specify log level and output. #35468
