Add support for build version qualifiers.

[dblock]

Coming from opensearch-project/opensearch-build#1632, add support for -Dbuild.version_qualifier=.

The distribution build process now supports passing additional optional qualifiers other than the 3 digit versions, e.g. 2.0.0-alpha1. Add the ability to pass additional qualifier to build scripts, and generate artifacts with a version that includes the qualifier.
