1. 1. Motivation ##

The constructor of  com.mongodb.reactivestreams.client.internal.FindPublisherImpl#FindPublisherImpl creates a new instance of FindOptions, which is a waste of memory.

And MongoCollection doesn't allow developers to pass the instance of FindOptions (while update/count/delete operations allow passing their options)

We want to pass our own FindOptions instance to avoid recreating the same FindOptions instance.

1. 1. Solution ##

1. Expose a new parameter to pass FindOptions for find operations in MongoCollection

2. Allow pass custom FindOptions to com.mongodb.reactivestreams.client.internal.FindPublisherImpl#FindPublisherImpl
