dnsip: errors

[bobrippling]

Proposed change

This change permits users to leave the nameserver field of the DNS IP integration empty, in which case the default system resolver is used.

This avoids issues where a user may have a local device they want to resolve, but the default nameserver (208.67.222.222 / 2620:119:53::53) will not know about it. Instead the system's nameserver is now used.

This will only affect new instantions of the DNSIP integration, as existing uses of those nameservers will be saved in config.

Additionally, resolver errors are now logged, meaning errors (such as in the example above) are easier to track down.

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Deprecation (breaking change to happen in the future)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Additional information

Happy to make tweaks to the config flow if the existing changes aren't sufficient to indicate to a user that the resolver is optional. Perhaps we have a way of surfacing the resolver errors to the user too, instead of (now) just logging.

Sadly I'm not able to get tests to a state where I can run them locally. Will close this PR unless the feature is desired

This would remove one of the key functions e.g. myip.

I suggest instead we would put the name servers in a (advanced) section already in the config flow so advanced users could change it (but it still defaults to those nameservers which are currently there).

[gjohansson-ST]

As already mentioned above.
