Add re-release workflow (#479)

scylla-3.x branch does not publish jars.
Until this issue is fixed we can endup in situation when new version was
pushed to sonatype, merge into git, but never release.
As result tag is there, commits are there, but no packages on maven.
To fix that we need this workflow to re-release, but not create any tag
or commit.
