MongoServerError: The 'expireAfterSeconds' option is supported on '_ts' field only.

It appears we need to enable compatibility mode for COSMOS-hosted Mongo DB instances.
We propose to support this through the addition of an additional server setting - DB_TYPE. This will be MONGODB by default, with an alternative setting of COSMOS_MONGODB.
DB_TYPE=COSMOS_MONGODB will result in compatibility mode being enabled.
