Adding a build tool to create a helm charts tarball
The helm charts are packaged in rpms by the build process and the purpose of this script is to package all those artifacts together into a single tarball, for use by other components in StarlingX. Uses centos_helm.inc in each repo to determine what to search for. Currently tested with packages from stx-config and stx-upstream: openstack-helm-infra openstack-helm stx-openstack-helm Multiple tarballs are created, one per manifest. A calculated checksum.md5 is included in each tarball Story: 2004005 Task: 27933 Depends-On: I3727a15fbdadc345a104c2af3446aee845171309 Change-Id: I06259d27e8f25d0b05eecdea49b2365246ac3112 Signed-off-by: Al Bailey <Al.Bailey@windriver.com>
