Cut 2 deleted the stage probes and the tests that injected faults through them.
DirectoryStoreDurabilityTests takes the faults from held files instead:
FailedManifestReplaceKeepsPreviousGeneration,
SameStoredAtDifferentPayloadWritesADistinctPage, PullAllWaitsForHeldCommitLease,
MutationBlockedBehindFlushStaysDirty, FlushNeverOpensUnchangedPages,
MissingManifestIgnoresOrphanPagesAndFlushDeletesThem,
TamperedPageFailsLoadNamingPage.
The tampered page surfaces as an AggregateException from the parallel page
load whose message names the page; the test asserts the page is named.
