Adding new package version attributes maturity, license, and license_url. Introducing the concept of dynamic package version attributes so that these can be added easily in the future. The attributes are driven by a metadata spec returned by the proc apm::package_version::attributes::get_spec.The attributes are stored in the skinny table apm_package_version_attr and managed through the Tcl API in namespace apm::package_version::attributes. Changing the parse and generate info XML file procs to use the dynamic attributes. Adding the dynamic attributes to the manifest XML file as well. The attributes are editable in the APM admin UI.
