Description

Briefly describe what this PR accomplishes and why it's needed.

Our serve ingress keeps running into below error related to uvloop under heavy load

File descriptor 97 is used by transport

The uvloop team have a PR to fix it, but seems like no one is working on it

One of workaround mentioned in the (PR) is to just turn off uvloop .
We tried it in our env and didn't see any major performance difference
Hence as part of this PR, we are defining a new env for controlling UVloop
