Add an AWS operator for Create RDS Database

[ferruzzi]

Description

@eladkal suggested we add the operator and then incorporate it into #23681. I have a little bit of a backlog right now trying to get the System Tests up and running for AWS, but if someone wants to get to it before me, it should be a pretty easy first contribution.

The required API call is documented here and I'm happy to help with any questions and./or help review it if someone wants to take a stab at it before I get the time.
