consul/connect: Enable running multiple ingress gateways per Nomad agent 

Connect ingress gateway services were being registered into Consul without
an explicit deterministic service ID. Consul would generate one automatically,
but then Nomad would have no way to register a second gateway on the same agent
as it would not supply 'proxy-id' during envoy bootstrap.

Set the ServiceID for gateways, and supply 'proxy-id' when doing envoy bootstrap.

Fixes #9834

BUG FIXES:
* consul/connect: Fixed a bug where gateway proxy connection default timeout not set [[GH-9851](https://github.com/hashicorp/nomad/pull/9851)]
* consul/connect: Fixed a bug prevening more than one connect gateway per Nomad client [[GH-9849](https://github.com/hashicorp/nomad/pull/9849)]
* scheduler: Fixed a bug where shared ports were not persisted during inplace updates for service jobs. [[GH-9830](https://github.com/hashicorp/nomad/issues/9830)]
