gfe-relnote: (n/a) Change SetQuicFlag to take the flag variable directly instead of a pointer to it. Refactor for Envoy integration, no behavior change.

This is needed for Envoy integration because the current syntax(SetQuicFlag(&FLAG_foo)) requires FLAG_foo is a valid c++ identifier, which is not the case in Envoy.
