---------------------------------------------------------------------
Test was committed failing on Windows by CASSANDRA-7357. There was expected
state in the WindowsFailedSnapshotTracker that wasn't setup tripping this
assertion, and when that state is initialized the test fails as it's expecting
snapshots to be off-disk when delete is requested. Given memory-mapped files on
Windows we can't guarantee those snapshots will be deleted until either JVM
shutdown or next C* start.
This is all moot as we don't use ephemeral snapshots on Windows since we don't
allow snapshot-based repair. Trivial patch attached that skips this test on
Windows with a comment as to why.

> Did some juggling to get the state cleared/prepped when I wrote the test but
> apparently it's intermittently failing with the following:
> {noformat}
> junit.framework.AssertionFailedError
> at
> org.apache.cassandra.db.WindowsFailedSnapshotTracker.handleFailedSnapshot(WindowsFailedSnapshotTracker.java:104)
> at
> org.apache.cassandra.db.Directories.clearSnapshot(Directories.java:741)

> at
> org.apache.cassandra.db.ColumnFamilyStoreTest.testClearEphemeralSnapshots(ColumnFamilyStoreTest.java:1555)
> {noformat}
> I assume it's something trivial (having not yet looked into it at all).
