Make the verify OT&E action more performant

Browse source 
As previously written, it loaded up all history entries into memory and then
processed them. This was OOMing for some registrars on sandbox who had performed
a large number of testing actions, most of them long OT&E was passed.

This commit changes the verify OT&E action to stream the history entries in
batches, ordered by when they were made, and then terminates once all tests have
passed. This prevents OOMing because only a single batch of history entries need
reside in memory at once.

This does necessitate the creation of a new composite Datastore index on
HistoryEntry, so we'll need to run the ResaveAllHistoryEntriesAction in sandbox
after this change is deployed before the new verify OT&E code will work.

Note that the "history viewer" is long dead, but that the pre-existing index
on HistoryEntries is still used for many other purposes.
