Explore making that remote write failure less intrusive

Users are encountering an issue when attempting to "Create hostedcluster on BM+disconnected+ipv6 through MCE." This issue is related to the default settings of `--enable-uwm-telemetry-remote-write` being true. Which might mean that that in the default case with disconnected and whatever is configured in the configmap for UWM e.g (
  minBackoff: 1s
url: https://infogw.api.openshift.com/metrics/v1/receive
Is not reachable with disconneced.

So we should look into reporting the issue and remdiating vs. Fataling on it for disconnected scenarios.

In MCE 2.4, we currently document to disable `--enable-uwm-telemetry-remote-write` if the hosted control plane feature is used in a disconnected environment.

Once this Jira is fixed, the documentation needs to be removed, users do not need to disable `--enable-uwm-telemetry-remote-write`. The HO is expected to fail gracefully on `--enable-uwm-telemetry-remote-write` and continue to be operational.
