    Replaces extra requirement with provider package. The intention here is that when

    separately. This is not needed and even harmful, because in case of future versions of
    the provider, the requirements might change, so hard-coding requirements from the version
    that was available at the release time might cause dependency conflicts in the future.

    Say for example that you have salesforce provider with those deps:

    { 'salesforce': ['simple-salesforce>=1.0.0', 'tableauserverclient'] }

    Initially ['salesforce'] extra has those requirements and it works like that when you install
    it when INSTALL_PROVIDERS_FROM_SOURCES is set to `true` (during the development). However, when
    the production installation is used, The dependencies are changed:

    { 'salesforce': ['apache-airflow-providers-salesforce'] }

            ['simple-salesforce>=1.0.0', 'tableauserverclient']

    So transitively 'salesforce' extra has all the requirements it needs and in case the provider
    changes it's dependencies, they will transitively change as well.

    In the constraint mechanism we save both - provider versions and it's dependencies
    version, which means that installation using constraints is repeatable.
