Rename "extra" option to "raw"

[ptpaterson]

Problem

"raw" may not be a perfect name for this option, but I believe it is a step forward from "extra"

Solution

rename the option and all the argv values from "extra" to "raw"

Result

no functional changes, just the name.

Testing

no functional changes, just the name.

Maybe it's worth saying it's the data from the JS drivers?

I know there's been some confusion/expectation it would be the raw http body.

Like in the help description? Or via name convention?

I think it would be nice to have the option to return the wire protocol, but I otherwise like the consistency with returning the data field in the QuerySuccess object in whatever format you would have received without the --extra/--raw option.
