More general class loading instrumentation

[trask]

Nice to be able to contribute something back! From open-telemetry/opentelemetry-java-instrumentation#152

[trask]

eeek! that's what i get for turning off test_ibm8 on opentelemetry-auto-instr-java to save $$

[tylerbenson]

Why did the jmxfetch submodule get updated?

[trask]

@tylerbenson Oops! That was unintentional, fixed now.

Thanks for sharing it back!
