    Add conditional version retrieval from setup. (#12853)
    
    When airflow is not installed as package (for example for local
    development from sources) there is no package metadata.
    
    Many of our unit tests use the version field and they fail if they
    are run within virtual environment where airflow is not installed
    as package (for example in IntelliJ this is default setting.
    
    This PR adds fall-back to read airflow version from setup in
    case it cannot be read from package metadata.
