Fix NPE in registry_tool when creating or updating a TLD with a dns writer

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.
