Fix a bug where consul service definitions would not be updated if changes
were made to the service in the Nomad job. Currently this only fixes the
bug for cases where the fix is a matter of updating consul agent's service
registration. There is related bug where destructive changes are required
(see #6877) which will be fixed in another PR.
The enable_tag_override configuration setting for the parent service is
applied to the sidecar service.
Fixes#6459
Without a `LocalServicePort`, Connect services will try to use the
mapped port even when delivering traffic locally. A user can override
this behavior by pinning the port value in the `service` stanza but
this prevents us from using the Consul service name to reach the
service.
This commits configures the Consul proxy with its `LocalServicePort`
and `LocalServiceAddress` fields.
