Description:
ATM we scan each data directory four times. We could easily reduce that to at
least two, maybe to one.
# pre-flight (startup tests) scrub
# pre-flight (startup tests) sstable min version
# {{ColumnFamilyStore.createColumnFamilyStore}}
# {{ColumnFamilyStore.}} (if {{loadSSTables==true}})
First two pre-flight tests could be combined to one and 3+4 could also be
combined, as both appear at pretty related code paths.

ATM we scan each data directory four times. We could easily reduce that to at
