We have a use-case that often requires request payloads larger than the current MAX_CONTENT_LENGTH (https://github.com/GoogleCloudPlatform/functions-framework-python/blob/master/src/functions_framework/__init__.py#L41).

Functions Framework is intended to be run on K8ts or Cloud Run, both of which can be configured to handle larger requests than the current MAX_CONTENT_LENGTH, so configuring it to be larger would open up the library for more use cases.
