Golang cluster specifier

The HTTP Golang cluster specifier allows Golang <https://go.dev/>_ to choose router cluster and makes it easier to extend Envoy.

Go cluster specifier plugins can be recompiled independently of Envoy.

.. warning:: 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!
