[zuul3] zuul2 -> zuul3 migration

Hi Team, We would like to migrate our Third Party CI[1] from zuul2 to zuul3. We have a lot of Jenkins jobs initially based on infra project-config-example But I guess we need to re write all the jobs now to support ansible. Any guide/example/tips are highly appreciated.
