The load tests used to directly build EPP, but that becomes
problematic for an upcoming CL that refactors a lot of the
EPP flow code. Instead, use the existing tool endpoint
(conveniently, LoadTestAction is already in the tools module).
This required changing the EppToolServlet to get its
xml from a param rather than from the request payload,
since task queues won't allow both a payload and request
params on the same task.

ReferenceUnion is a hack to work around the mismatch between how
we store references (by roid) and how they are represented in EPP
(by foreign key). If it ever needed to exist (not entirely clear...)
it should have remained tightly scoped within the domain commands
and resources. Instead it has leaked everywhere in the project,
causing lots of boilerplate. This CL hides all of that behind
standard Refs, and should be followed by work to remove ReferenceUnion
completely.

The tool needs to:
* Replace all hosts on a domain with a provided set of hosts
* Add 3 server locks to the domain
* Print an undo command that restores the domain to its original state
