Review Comment:
I think its ok here. In the past tablet col fam was meant to hold info
needed by clients and had its own column family. However I am not sure how
relevant that it. I think we need to reevaluate the metadata schema and
locality groups against the different scan patterns. Also should probably
look into passing hints for certain metadata scans that cause them to not use
cache or use cache. Should probably do that after the dust settles on the
elasticity changes.
