Get all scanners with no filtering based on TTL (that happens further down the line).
@param cacheBlocks  cache the blocks or not
@param usePread     true to use pread, false if not
@param isCompaction true if the scanner is created for compaction
@param matcher      the scan query matcher
@param startRow     the start row
@param stopRow      the stop row
@param readPt       the read point of the current scan
@return all scanners for this store
