Split tooling into CLI and class library

[JPercival]

Description
Splits the cqf-tooling project into a core class library project and a CLI project. This allows the users of the core library to select the platform-appropriate Jaxb/Jackson runtime components. This is just a first pass. I noticed while doing this work that there are two Jaxb implementations on the classpath, as well as two test frameworks. Some further work is needed to fully disentangle all the dependencies.

I also noticed some test content was duplicated. This was removed.

There is an additional refreshIG test that has been enabled, so the test coverage for this PR is actually higher than it was previously.

There's a breaking change, which is that the executable jar (or "fat jar") is now called "tooling-cli".
