Ability to ingest records from other sources

[bennybp]

Description

This adds the basics of external record ingestion. That is, users will now have the ability to import records from other sources into the QCFractal server.

Basically, you can now send/upload a QCPortal record or QCSchema result. It will create a record on the server that behaves identically to other records.

This will allow for running computations in customized ways and uploading the results, and also for transferring between QCFractal instances.

Some limitations:

• QCSchema results can be imported, but they must be full "successful" computations
• QCPortal records that have a state of error, cancelled, invalid, deleted cannot be reset
• QCPortal records that are waiting will not be run on the new server
• The new records must be attached to a project (not loose on the server)

Right now, only individual records can be imported - datasets are coming soon.

This PR also adds some useful functions, such as comparing records

Few more things to do:

• Better error handling in the server-side ingestion functions (returning InsertMetadata, etc)
• Add tests for importing into projects

Status

• Code base linted
• Ready to go
