Golang cluster specifier
The HTTP Golang cluster specifier allows Golang to choose router cluster and makes it easier to extend Envoy.
Go cluster specifier plugins can be recompiled independently of Envoy.
The Envoy Golang cluster specifier is designed to be run with the
GODEBUG=cgocheck=0 environment variable set.
This disables the cgo pointer check.
Failure to set this environment variable will cause Envoy to crash!
