  - AAA-168: Remove embedded h2 dependency

    This was code inherited from a long time ago and punted around AAA
    without any real cleanup.  I am not sure why the original authors
    decided to embed the dependency rather than just import it, but this
    causes several issues.  This patch removes the embedded h2 dependency
    in favor of direct import.  While I recognize that other parts of
    ImportPackage need to be cleaned, they will be done in a subsequent
    patch since they are separate concepts than what is done here.
    In other words, expect follow-ups to continuing cleaning.

    aaa-cli-jar relied on aaa-shiro shading the com.h2database:h2 jar,
    so I instead added it as a compile time dependency for the module
    and extracted the appropriate files for the generated jar in the
    maven-shade-plugin configuration.
