feat(o11y): Configure opentelemetry filter at runtime (#7701)

Enabling or disabling tracing at runtime can be useful to debug issues with nodes running too slow. This allows us to avoid restarting a node, which is known to have a rather large impact on the node.

Tested that all combinations of logs verbosity and opentelemetry verbosity work well together.
Tested by reconfiguring logging as follows:

```
echo '{"verbose_module":"", "opentelemetry_level": "DEBUG"}' > ~/.near/betanet/log_config.json ; killall -SIGHUP neard
```
