The multi feature migration test works by having two system index
features that are to be upgraded. The reindexing of the system indices
of those features is done in sequence by the system index migrator, and
the test has an assertBusy that waits for all the migrations to
complete. Unfortunately assertBusy backs off exponentially, so it isn't
great for quickly resuming the test once the underlying assertion
becomes true, since the condition might change shortly after an
iteration, and then have to wait for a long backoff.

This commit adds a latch which will count down all the executions of the
test plugins, so that the assert busy will not be run until after all
the indexes have migrated.
