- Add one full kick workflows for doing milestone or release.
- Use new central infra for all workflows
- Still keep old manual central workflows as we probably need
those until branches are fixes to use new workflows for central.
- Separate artifactory build names so that we have unique ones
for snapshot/milestone/release per branch as otherwise
jfrog artifact download might be inaccurate.
- Use github environments to pause workflow for promotion and
central sync to be able manually check that staged and released
artifacts looks ok.
- Add tweaks to gradle build to ease switching to milestone, release
or next dev version.
