This ticket was split from DRIVERS-2656, please see that ticket for a detailed description.

AC
Remove the following deprecations:

• GridFSFile: contentType, aliases
• GridFSBucketWriteStreamOptions: contentType, aliases
• CloseOptions interface
• ResumeOptions interface
• client options: useNewUrlParser, useUnifiedTopology
• CreateCollectionOptions -> autoIndexId (deprecated in server 3.2, removed in server 8.2; several drivers have already removed it)
• the generic TSchema param from FindOptions interface
• ClientMetadataOptions interface (the code comment says make internal, but it is unused, so it can be deleted)
• FindOneOptions deprecations. This must result in a FindOneOptions interface that does not inherit from FindOptions, but contains a subset of the FindOptions in order to not be considered equal with FindOptions.
• ReadPreference: minWireVersion
• ServerCapabilities
• `CommandOperationOptions` -> `retryWrites`

Make internal the following deprecations:

• ClientSession -> transaction
• class Transaction (and remove internal deprecation markers)
• CancellationToken
