Description

Whilst debugging CASSANDRA-12457, I noticed that if we don't stop compactions when draining the 2.2 node, then we may fail to restart the node after upgrading to 3.0.

This is because sstable names in 2.2 have been changed from la to lb but LEGACY_TMP_REGEX_STR in Descriptor.java doe not match lb sstables and therefore it won't clean or ignore temporary files.
