Description

CASSANDRA-8671 added the ability to change the data directory based on the compaction strategy.

Since nothing uses this yet we haven't hit any issues but reading the code I see potential bugs for things like Transaction log cleanup and CFS initialization since these all use the default Directories location from the yaml.

• Directories is passed into CFS constructor then possibly disregarded.
• Startup checks like scrubDataDirectories are all using default Directories locations.
• StandaloneSSTableUtil
