Osquery configuration and data must be stored per-organization

[RebeccaMahany]

Store osquery data (node key, uuid, config, keys, ATC config, KATC config) in bbolt and in sqlite per-organization as well as globally. (We want to keep storing globally because this change must be backwards compatible.) To start, store everything under the current tenant. We may want to key off the node key, or a "registration ID" that doesn't yet exist in K2; we don't want to key off munemo in case we end up wanting multiple instances per single tenant.
