Infra Manager updates Service failed and trigger svc/deployment wrongly

Description:

What issue is being seen? Describe what should be happening instead of
the bug, for example: Envoy should not crash, the expected value isn't
returned, etc.

Infra Manager updates Service Failed and Wrongly

• Update Service Failed:

It can be reproduced after update Gateway CR.

• Update Service Wrongly:

We should not simply use deep copy to compare if svc has changed: https://github.com/envoyproxy/gateway/blob/main/internal/infrastructure/kubernetes/service.go#L95

We should just compare a couple of specific vars. (Some vars in svc spec are fullfiled by k8s itself).

When restarting envoy gateway, without anychanges to gateway CR, it will be updated wrongly.

Now that #702 has merged, can you confirm this bug still exists?

Close this since it is not reproduced again.
