* MethodsConfigurationParser is moved to javaagent-tooling - it's only used in some instrumentation modules
* BootstrapPackagePrefixesHolder is moved to javaagent-api - it just needs to be in the bootstrap CL for the classloader instrumentation, so it does not necessarily need to be instrumentation-api
* testing-common refactoring: replace direct AgentTestRunner usage with spock spec
* Updated instrumentation docs
* Fix reactor-core library tests
ReactorCoreTest was getting a tracer from GlobalOpenTelemetry before LibraryTestTrait had a change to initialize the SDK
