refactor: switches EDC over to using the runtime-metamodel library

[paullatzelsperger]

What this PR changes/adds

Some of the metamodel annotations and classes have been relocated into the runtime-metamodel library, which is available as Maven artifact. Specifically the following things were done:

• remove tooling/
• remove metamodel annotations like @Inject, @Provides, etc.
• add dependency onto org.eclipse.dataspaceconnector:runtime-metamodel:0.0.1-SNAPSHOT
• adapt all affected import statements

Why it does that

Both EDC and the documentation generator Gradle plugin ("autodoc") need access to this information, so we needed to move it out to break a cyclic dependency.

Further notes

• runtime-metamodel will be available as 0.0.1-SNAPSHOT until such time as we have a decision on how we deal with these components in regard to versioning, group ids, etc.

• the amount of files changed is mostly caused by updated import statements

Could you pls also update the codeowners file?

In addition, I was wondering whether our decision to extract the metamodel should be documented by a decision record? I know we have not done this for the other components, however, this is a new dependency the connector relies on, so it would be nice to write it down and link to the decision record 2022-08-04-documentation-automation as this already talks about using a Gradle plugin.

Could you pls also update the codeowners file?

Sure. Thanks for noticing.

Decision record

yup I agree, will create one
