Remove duplicated connection-type within the provider

[Taragolis]

Remove duplicated connection type for amazon and databricks providers.

aws provided by airflow.providers.amazon.aws.hooks.base_aws.AwsGenericHook
databricks provided by airflow.providers.databricks.hooks.databricks.DatabricksHook

Seem like the actual order in connection-types in provider.yaml the only thing that really matter, if provider contains multiple different hook-class-name with the same connection-type:

• The first hook-class-name with listed would use in the UI/API/CLI for fields names and testing connection
• All other would be ignored, the warning only shows if same connection-type exists in the different providers

airflow/airflow/providers_manager.py

Lines 529 to 539 in 55d1146

	provider_uses_connection_types = False
	connection_types = provider.data.get("connection-types")
	if connection_types:
	for connection_type_dict in connection_types:
	connection_type = connection_type_dict['connection-type']
	hook_class_name = connection_type_dict['hook-class-name']
	hook_class_names_registered.add(hook_class_name)
	already_registered = self._hook_provider_dict.get(connection_type)
	if already_registered:
	if already_registered.package_name != package_name:
	already_registered_warning_connection_types.add(connection_type)

Might be also good idea to warn users if already_registered connection-type exists in the same provider.
