http.wait_for_successful_query module doesn't support 'request_interval'

[Oloremo]

Description of Issue

There is a slight difference between http.wait_for_successful_query state and module.
State does support request_interval kwargs while module doesn't.

Running this module without this feature creates a http connections flood since it trying to repeat http connection as soon as possible.

Why don't I just use a state? Well, first of all I think it's inconsistency which needs to be fixed. Second, I'm trying to combine loop.until with http.wait_for_successful_query to be able to parse the serialized output of http endpoints since match feature of http utils is not good for that, and I get a http connection flood.

Steps to Reproduce Issue

You can run it like:
salt-call http.wait_for_successful_query http://127.0.0.1:7777 wait_for=10 -l debug
And just check how many http connection will be executed.

While using it as a state you can throttle this by request_interval kwargs.

Versions Report

I'm using 2019.02 but all version are affected.
