Do not merge/review! Reproducer for: Muzzle does not check abstract method at runtime

[pavolloffay]

Reproducer for #1337.

Steps to reproduce:

git fetch origin origin/1354/head:PR1354
git checkout PR1354

And sample app, cone https://github.com/pavolloffay/sample-apps/tree/traceable

./gradlew build
OTEL_EXPORTER=otlp java -agentlib:jdwp="transport=dt_socket,server=y,suspend=n,address=5000" -javaagent:${HOME}/projects/opentelemetry/opentelemetry-java-instrumentation/javaagent/build/libs/opentelemetry-javaagent-0.9.0-SNAPSHOT-all.jar  -jar  "http/servers/jetty/jetty-servlet31x/build/libs/sample-jetty-app.jar" 7311 7312 

Now search for Server exception at doPost: java.lang.AbstractMethodError: Missing implementation of resolved method 'abstract boolean isReady()' of abstract class javax.servlet.ServletInputStream. in the stdout.

The issue is in this class https://github.com/pavolloffay/opentelemetry-auto-instr-java/blob/muzzle-runtime-abstract-method/instrumentation/servlet/servlet-3.0/src/main/java/io/opentelemetry/instrumentation/auto/servlet/v3_0/bodycapture/BufferingHttpServletRequest.java#L254. The muzzle fails the build correctly but does not recognize API mismatch at runtime and the instrumentation is loaded.
