Title: Fixed non-persistent connections handling with AWS DNS

There are many places like this:
`@persistent = options[:persistent] || false`

So there is no way to set `@persistent` to false.
Seems like other backends have the same issues too.

I don't know the best way to fix, so just notice you about the bug.
