I forgot to inject the CreateTldCommand/UpdateTldCommand commands, which now
need to be injected so that the list of available DnsWriter implementations is
instantiated. This CL also adds a new DI Set<String> with just the name of the
writer, so that the instantiated writer map (which may have many DI dependencies)
doesn't need to be pulled in.

This is one of several CLs in a sequence for allowing per-TLD DNS
implementations.

The plumbing to support different DnsWriter implementations per TLD
using DI will come in a later CL.
