This is a temporary change used for b/71607306 only, and has TODOs to revert at
every change once the bug is done.
We want to check how Cloud DNS handles large (1M+ domain) zones, especially
during resigning. However, due to a separate bug (b/70980350, and maybe another
one) we can't currently create such a large zone in nomulus within the required
4 day timeframe. The most we managed is 300k domains.
We could wait until the bug is fixed, but if there's a problem with Cloud DNS -
we want to find out as fast as possible. Hence, this CL that allows us to
register 1M domains by creating "just" 100k domains in nomulus.
The CL creates a new "MultiplyingCloudDnsWriter" writer, that when publishing a
domain, pretends that we are publishing 10 domains (with 9 additional
"fictional" domains, that get their Datastore data from the actual domain).

Before pushing an update to Cloud DNS, the CloudDnsWriter needs to read all the domain RRSs from Cloud DNS one by one to know what to delete.
Doing so sequentially results in update times that are too long (approx 200ms per domain, which is 20 seconds per batch of 100) severely limiting our QPS.
This CL uses Concurrent threading to do the Cloud DNS queries in parallel. Unfortunately, my preferred method (Set.parallelStream) doesn't work on App Engine :(
This reduces the per-item time from 200ms to 80ms, which can be further reduced to 50ms if we remove the rate limiter (currently set to 20 per second).

This removes some qualifiers that aren't necessary (e.g. public/abstract on interfaces, private on enum constructors, final on private methods, static on nested interfaces/enums), uses Java 8 lambdas and features where that's an improvement

This was a surprisingly involved change. Some of the difficulties included
java.util.Optional purposely not being Serializable (so I had to move a
few Optionals in mapreduce classes to @Nullable) and having to add the Truth
Java8 extension library for assertion support.

Add cloudDns.{rootUrl, servicePath} to allow us to point an environment at the
Cloud DNS staging API for testing. Make sandbox and alpha point to staging.

This is the final preparatory step necessary in order to load and load
configuration from YAML in a static context and then provide it either via
Dagger (using ConfigModule) or through RegistryConfig's existing static
functions.
