Add command to update a DNS record set

[BartG95]

Currently, I can add, remove and update a single DNS record at a time. But sometimes, I have multiple records for the same Name and Type. For example, multiple A records, or multiple TLSA records.

What I want: a command to get the record set for a given Name and Type, modify it locally, and then upload it.

For example:

tipctl -t domain:dns:updatednsentry example.com @ 3600 A 0.0.0.0 0.0.0.1

This should create (or update) two A records.
