Remove anorm-2.0 instrumentation module

[jasonjkeller]

This deletes the anorm-2.0 instrumentation module as the artifacts that it instrumented can no longer be publicly downloaded. Furthermore, the range of artifacts that it instrumented ([2.0,2.3-M1)) were all released in 2015 or prior and are likely not worth supporting any longer.

Usage of this version of the anorm instrumentation is fairly low:

Compared to more popular instrumentation modules:

This was incorrectly updated to compile against com.typesafe.play:anorm_2.10:2.3.9 because that is the oldest version available on maven. However, this instrumentation module is only supposed to instrument anorm versions 2.0 up to, but not including 2.3-M1. Thus it was compiling against an unsupported version.

This meant that the instrumentation was weaving a method that no longer existed in version 2.3.9 which was leading to the following WeaveViolations:

     WeaveViolation{type=METHOD_NEW_CALL_ORIGINAL_UNSUPPORTED, clazz=anorm/Sql$, method=as(Lanorm/ResultSetParser;Ljava/sql/ResultSet;)Ljava/lang/Object;}
     WeaveViolation{type=METHOD_NEW_NON_PRIVATE_UNSUPPORTED, clazz=anorm/Sql$, method=as(Lanorm/ResultSetParser;Ljava/sql/ResultSet;)Ljava/lang/Object;}
