Support overriding the profile_config per dbt node or folder using config

[tatiana]

Allow users to override profile_config per operator or folder using config. Extends the work introduced by @wornjs in #1339, when we started supporting operator-level arguments defined in the dbt project/model YAML.

This PR includes a generic implementation that introduces the [meta][cosmos][profile_config] section, at the same level as operator_kwargs, and ensures these configs override the original profile config.

Example overriding a profile_config that uses profiles_yml_filepath:

      +meta:
        cosmos:
          operator_kwargs:
              (...)
          profile_config:
             profile_name: non_default_profile
             target_name: stage
             profiles_yml_filepath: /some/dir/profiles.yml

Example of an interface when using profile_mapping:

      +meta:
        cosmos:
          operator_kwargs:
            (...)    
          profile_config:
             profile_name: non_default_profile
             target_name: stage
             profile_mapping:
               conn_id: non_default_connection
               profile_args:
                 schema: non_default_schema

@wornjs @dwreeves @pankajastro @pankajkoti would love your thoughts. Please look at the description and the current/ possible alternative implementation. I'm happy to hear other ideas as well! I'd rather take a bit longer and have an interface that makes sense.
