Description

The SAI versioning does not consider having multiple on-disk per-column index versions against a single SSTable.

The IndexDescriptor handles the versioning of all the index components for an SSTable but does not recognise multiple on-disk per-column versions.

The IndexDescriptor needs to look at all on-disk components and maintain a mapping of component to version.

NOTE: This is a precursor ticket to any ticket involving an on-disk version change for 5.x
