Instrumentation Configuration Utilities

[jaydeluca]

All of our configuration options are currently stored as standard system properties. We need to create utilities to be able to convert from system property to the declarative configuration equivalent.

See the POC example

Here is the source for the "special" mapped properties: https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/declarative-config-bridge/src/main/java/io/opentelemetry/instrumentation/config/bridge/ConfigPropertiesBackedDeclarativeConfigProperties.java

Hi @jaydeluca! I'd like to work on this one.

I went through the POC example and compared the Java sepcial_mapping with the existing TypeScript config-name-converter.ts.
I can see there are some missing mappings that need to be added, along with tests to cover the conversion logic.

Happy to take this on!
