Make OTLP receiver listen on all IPs again (#5739)

## Which problem is this PR solving?
- Resolves #5737

## Description of the changes
- Revert #5734
- Default OTLP receiver endpoints to `:port` instead of relying on OTEL
Collector defaults
- Clean up tests to use ephemeral ports when possible

## How was this change tested?
- Tested similar to #5734 by using `COLLECTOR_OTLP_HTTP_HOST_PORT=:4318`
