[Config] Support Trace Methods wildcards

[jackshirazi]

Classic agent link

• https://www.elastic.co/guide/en/apm/agent/java/current/config-core.html#config-trace-methods

What it does

Defines a list of methods for which to create a transaction or span.

Implementation difficulty, location, and dynamism

• The otel equivalent of trace_methods is otel.instrumentation.methods.include which doesn't support wildcards https://opentelemetry.io/docs/instrumentation/java/automatic/annotations/#creating-spans-around-methods-with-otelinstrumentationmethodsinclude
• If wildcard tracing is required, we will need to either
  -- use our implementation or
  -- implement it into the otel one
  -- or provide a utility that reads the class and generates the non-wildcard pattern
• Not currently dynamic, but maybe can make it so without too much trouble

@akhileshpok please feedback on whether wildcard support is needed, eg the classic agent allows org.example.MyClass#myMe*od to specify multiple packages/classes/methods whereas the current OpenTelemetry agent doesn't support wildcards and you need to explicitly define each method that will be traced
