Description

Currently there is a difference in the output if nodetool compactionstats command and sstable_tasks virtual table (originally introduced by CASSANDRA-14457). They need to be aligned. The differences are:

 

nodetool	VT	Comment
percentComplete	completion_ratio	column naming is different only
completed	progress	column naming is different only
compaction type	kind	column naming is different only
sstables	NA

Additionally, please, update necessary documentation.
