Problem Statement/Rationale

mongodump & mongorestore currently back up & restore collections with the encryptedFields property. This constitutes incomplete QE support that we're not ready to offer.

We should instead:

• Make mongodump fail on backing up QE collections.
• Make mongorestore warn when restoring QE collections that the QE portion is not restored.

Steps to Reproduce

In mongosh on the source:

use test
db.createCollection("qe", {encryptedFields: { fields: [ {path: "foo", bsonType: "string", queries: { queryType: "equality" }, keyId: UUID() } ] } })

Then, at the command line:

mongodump --authenticationDatabase=admin  --archive=qe.bson -d test -c qe $connStr1
mongorestore --authenticationDatabase=admin --archive=qe.bson --drop $connStr2

Finally, in mongosh on the destination:

use test
db.getCollectionInfos()

Expected Results

Dump should fail the archive creation. Restore should warn.

Actual Results

No error or warning happens in that process, so the restore leaves incomplete QE.
