Context

Currently the GridFS stream objects GridFSUploadStream and GridFSDownloadStream maintain the context used to construct them as a field. This is rather dangerous and can lead to context misuse.

Definition of done

Open a Go Routine where the context is defined to cancel:

ctx, cancel := context.WithDeadline()
go func() {
    <-someCondition 
    cancel()
}()

Specifically, use the pattern defined when checking a server: https://github.com/mongodb/mongo-go-driver/blob/d55b4b93d81c1850e86fab66857eda8156d63aa0/x/mongo/driver/topology/server.go#L590
