Is your feature request related to a problem? Please describe.
OpenTelemetry has a list of supported configurations that the LS Launcher is missing. Example:
DB statement sanitization: https://opentelemetry.io/docs/instrumentation/java/automatic/agent-config/#db-statement-sanitization

Describe the solution you'd like
Support all available config options for the OpenTelemetry agent.

Hey hey - all these configuration should work just fine. The Java Launcher simply pre-configures some parameters (e.g. OTLP ingestion path, OTLP headers), but anything else works fine and transparently. Are you having a specific problem or a use case is not working as expected?

@carlosalberto I can't log the db attributes in Lightstep.

1. added the OTEL_INSTRUMENTATION_COMMON_DB_STATEMENT_SANITIZER_ENABLED=false env var., I could still see ?.
2. tried adding -Dotel.instrumentation.common.db-statement-sanitizer.enabled=false, did not work, same ?.
3. tried adding otel.instrumentation.common.db-statement-sanitizer.enabled in the application.properties file, did not work, same ?.

I took a quick look to the project. [I might be missing something essential but...] it seems that some Opentelemetry configs are not read by the VariablesConverter class, so the agent is always configured with the default values, in this particular example: OTEL_INSTRUMENTATION_COMMON_DB_STATEMENT_SANITIZER_ENABLED=true

[carlosalberto]

Interesting. Variables converter pre-sets some values, but properties should flow transparently. Will take a second look to double check what's going on.

@carlosalberto any news on this?:)

Hi @jenni! Apologies for the delay here, @carlosalberto is coming back from PTO next week and will follow up here.

@codeboten @carlosalberto it's a pity that it's been 2 months since I opened this issue and haven't heard back from anyone. I have tried to look into it myself but I can't start the project as some environment variables are missing and there's no documentation on how to contribute here. I guess the best would be to add some docs or simply deprecate the repo.
