Migration: convert File objects to RuptureSet or InversionSolution objects

[chrisbc]

We want to migrate File objects to the new types as appropriate so the users can benefit from the new features for historic objects.

NB: API clients should be able to access these objects as Files using either File NodeID or Subclass NodeID

Done When

• convert to RuptureSet object when (define criteria [max_jump_dist, fault_model])
• convert to InversionSolution object when (define criteria [completion_energy, ])
• for each conversion....
  • delete old ES index entry (until
  • add new ES index entry
  • log object ID and other info for data audit
• pre conversion
  • copy PROD data to test bucket and validate entire process there, including UI
  • make backup Bucket
  • user comms
