Create the DLRN trunk builder

The creation of the new DLRN Trunk builder is done in two steps:

1. in rdo-infra/ansible-role-dlrn and inside the rdo-toolbox:

    cp files/centos9-master-dlrn-deps.repo files/centos9-$RDO_MASTER_RELEASE-dlrn-deps.repo
    cp files/centos9-master-rdo-trunk-runtime-deps.repo files/centos9-$RDO_MASTER_RELEASE-rdo-trunk-runtime-deps.repo
    sed -i "s/master/$RDO_MASTER_RELEASE/g" files/centos9-$RDO_MASTER_RELEASE-dlrn-deps.repo files/centos9-$RDO_MASTER_RELEASE-rdo-trunk-runtime-deps.repo
    sed -i "s/|master-uc/|$RDO_MASTER_RELEASE|master-uc/" tasks/worker.yml
    

   e.g: https://review.rdoproject.org/r/c/rdo-infra/ansible-role-dlrn/+/47053
   Note: the addition of the new release in index.html should be done after bootstrap process finished. Otherwise, users may assume it's stable whereas it's WIP.

2. in softwarefactory-project/sf-infra project
   e.g: https://softwarefactory-project.io/r/c/software-factory/sf-infra/+/27459
   and needs to be pushed with a Depends-On first patch
