ceph-ansible: refact project definition

This commit modifies the current project definitions:

1/ it uses the exclude keyword to avoid duplicating project
2/ it declares a new project to only use smithi nodes for 'large'
scenario testing (basically all scenario based on 'all_daemons'
scenario).
3/ exclude 'non_container-cephadm_adopt' for non_containerized
deployments
4/ reindent jobs section
