Allow MAX_URI_LEN to be configurable via ENV variable #3960
Description
Is your feature request related to a problem? Please describe.
Currently there is no way to override the hardcoded MAX_URI_LEN limit in hyper. So it cant be used with legacy systems which supports URI longer than 64K.

Describe the solution you'd like
ENV variable HYPER_MAX_URI_LEN to configure the desired max uri len. And use default if its not configured.
Describe alternatives you've considered
Currently no alternatives present apart of changing the legacy system which is close to impossible.
