The Functions Framework contract provides valuable guidance for all framework developers. We should explicitly alter the contract to allow for declarative function signatures.
Specifically:
Remove the requirement of a FUNCTION_SIGNATURE_TYPE environment variable if the function is specified declaratively.
Define the behavior for an unspecified FUNCTION_TARGET if the function is specified declaratively.
I suggest if a user only specified one function, we start that function. If a user specified multiple functions, we either fail or we prompt the user for which function to start.
