Rename hibernate modules

[trask]

The goal of this PR is for the module names to be usable directly as artifact names when we publish them to maven central.

Existing module paths were:

:instrumentation:hibernate:core-3.3
:instrumentation:hibernate:core-4.0
:instrumentation:hibernate:core-4.3
:instrumentation:hibernate (this has common code)

Initially I tried:

:instrumentation:hibernate:hibernate-3.3
:instrumentation:hibernate:hibernate-4.0
:instrumentation:hibernate:hibernate-4.3
:instrumentation:hibernate:hibernate-common

But gradle doesn't like having an empty parent :instrumentation:hibernate, so I ended up at

:instrumentation:hibernate-3.3
:instrumentation:hibernate-4.0
:instrumentation:hibernate-4.3
:instrumentation:hibernate-common

and re-mapping their project directories in settings.gradle to keep them under a top-level hibernate directory.

Another option is to keep

:instrumentation:hibernate-3.3
:instrumentation:hibernate-4.0
:instrumentation:hibernate-4.3
:instrumentation:hibernate-common

but remove the "grouping" directory and move these modules directly under instrumentation, then they wouldn't need re-mapping of their project directories.

Alternatively, if we are ok with the "grouping" directory pattern, we could add similar grouping directories for play, spring, netty and several others, which might help organize the instrumentation directory.

When I try with:

:instrumentation:hibernate:hibernate-3.3
:instrumentation:hibernate:hibernate-4.0
:instrumentation:hibernate:hibernate-4.3
:instrumentation:hibernate:hibernate-common

and put this hibernate.gradle into the hibernate directory:

plugins {
  id 'base'
}

I still get the error I was getting before:

A problem occurred configuring project ':instrumentation:hibernate'.
> Failed to notify project evaluation listener.
   > Could not get unknown property 'compileJava' for task set of type org.gradle.api.internal.tasks.DefaultTaskContainer.
   > Could not get unknown property 'compile' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer.

I pushed this attempt to https://github.com/trask/opentelemetry-auto-instr-java/tree/rename-hibernate-modules-2 in case anyone with more gradle-fu than me has time to review.

I gave the empty grouping module another shot (trying to level up my gradle little by little 😂).

It turned out my earlier issues with having empty grouping module was because ":instrumentation" parent is applying "stuff" to all children.

First I tried to conditionally apply that "stuff" inside of ":instrumentation" parent gradle file, but that didn't go very well, so I extracted the "stuff" out into a shared gradle file, and applied that inside of each instrumentation, and that worked out pretty good!
