* dnsimple: bug-fix SSHFP, add multi TXT support
The default logic for encoding SSHFP records was dropping the key and
hash algorithms and just posting the content, the `Can` check didn't
stop attempts to use SSHFP. So, implement SSHFP support.
DNSimple support multiple DNS strings in a TXT record, by representing
the payload as quoted strings already. This doesn't appear to be
documented, but it does actually work.
* Update docs support matrix too
* fix go fmt missing upstream
Tests failing on my branch for something broken upstream
* fix typo in error message
