* Add ci/find-current-version.sh to figure out versions of lts and feature branch based on repository state. * Do not use ZEEK_IMAGE_REPO for the local images that are expected to exist. * Only use IMAGE_NAME/IMAGE_TAG instead of the ARCH and MANIFEST versions that contained the very same values * Support and push additional tags In addition to the lts and feature tags, also push the base version tags. 5.0 or 5.1 such that someone pulling zeek/zeek:5.0 will get the most recent available 5.0 patch release.
