Dialogue fails fast when existing channels are revoked from DNS

[carterkozak]

We don't want to spend ages retrying requests to dead nodes, where we expect every attempt to result in a connect timeout. It's much better to fail quickly rather than retry+backoff for minutes.

Dialogue fails fast when existing channels are revoked from DNS

Possible downsides?

if dns entries disappear and reappear, we may have failed requests for nothing. It's possible dns entires may be revoked while requests are still routable, but I don't think we should prioritize this case as it's generally not something we expect to support.

What do the change types mean?

• feature: A new feature of the service.
• improvement: An incremental improvement in the functionality or operation of the service.
• fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
• break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
  and external consumers of the service's API (e.g. customer-written software or integrations).
• deprecation: Advertises the intention to remove service functionality without any change to the
  operation of the service itself.
• manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
  performing database surgery, ...) at the time of upgrade for it to succeed.
• migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?

• ❗The break and manual task changelog types will result in a major release!
• 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
• ✨ All others will result in a minor version release.
