Add in-development version support

This adds support for in-development versioning of jars and wheels. Specifically, this PR translates the java version qualifier (anything after "-") to a python "local version label" (`<public version identifier>[+<local version label>]`). For example, the java version "1.2.3-SNAPSHOT" becomes python version "1.2.3+SNAPSHOT"; the java version "4.5.6-my-custom-build123" becomes python version "4.5.6+my.custom.build123". By using a "local version identifier", these wheels become development-only artifacts - they can't be publicly published. While we could contemplate using "development release segments" (ie, python versios that look like "X.Y.Z.devN"), we wouldn't be able to generally translate java versions to python versions without enforcing more structure onto our java versions.

As an added benefit, this PR also reduces some of the duplication of version numbers by sourcing the version number as appropriate during the wheel building process; and then also in the runtime python code, sourcing the version information via the appropriate importlib metadata APIs.
