Make dnspython package is optional
This PR make dnspython package optional, due to deliverability is optional as well.
It reduces installed dependencies if we don't check deliverability. Probably CHECK_DELIVERABILITY constant also should be changed to False, but it's change default behavior.
I'm not opposed to the idea, but it would have to wait for the next major version update (e.g. a 3.x) since it would change default behavior, and at this time I don't really foresee a 3.x because I don't see any other changes motivated for it.
