Description

*Title*: uhv: detect or add tests for duplicate headers

*Description*:
UHV is currently unable to detect when duplicate headers are sent because the codec will have concatenated duplicate header values into a list by the time UHV is run. The UHV component should either be able to detect duplicate headers, to enforce headers that can only be specified once, or additional unit tests should be added to validate the correct behavior.
