LakeHouse

When user creates a Trinity LakeHouse, the LakeHouse definition must be determined upfront. An update to the definition would entail a potentially expensive change of the TrinityLake tree. For example, changing the maximum object size or file size would entail re-encode all the keys in the tree.
