What Does This Do

Previously, the Baggage Cache implemented injected incoming headers if no modification to baggage was made while ignoring limits. In order to be in compliance with limits, this PR adds support to truncate the baggage cache if limits are violated. Furthermore, Java does not support sending non-ascii characters in http headers. This PR also forcefully builds a outgoing baggage header if the incoming header includes non-encoded non-ascii characters by disabling the cache when extracting such headers.

Motivation

Additional Notes

Verified through unit tests and system-tests in test_baggage.py.
