Allow configuration of upstream connection limits in Envoy (#6829)
* Adds 'limits' field to the upstream configuration of a connect proxy

This allows a user to configure the envoy connect proxy with
'max_connections', 'max_queued_requests', and 'max_concurrent_requests'. These
values are defined in the local proxy on a per-service instance basis
and should thus NOT be thought of as a global-level or even service-level value.
