Exredis.query() without client parameter. (using defaultclient)

[JeongHoon Baek]

Exredis.Api has no-client parameter methods using defaultclient, but Exredis.query() doesn't.

I did it, because query function must be raw, for low-level querying.
API contains functions that we can execute without client argument for simple cases, like unit tests.
But you can implement it, if you want.

Then, how about changing "defaultclient" to public function?

Current defaultclient is private, so I have to add same code in my application.

Yep, you can implement it, I will accept your PR.
