Description

It's possible to to write a response out directly , without creating the SolrDocument Objects if there are no transformers. 
So, we may use a new flag to use this mode . When enabled ,

• it serializes docs out to the stream without creating any Objects
• it uses a serialized format for document cache

Essentially, the cost of writing response out will be similar to the /export handler. Traditional transformers may not work in this mode.

A request would look as follows . The extra flag fastmode=true will switch the writing to this mode.
