allow for the instanceProfile SDK provider

Problem/Motivation

Sometimes the organization security posture won't allow for long lasting keys. The AWS SDK allows for the use of an Instance Profile which will provide the server instance with its own access without needing to use keys. The AWS SDK provides for this as well by using the Instance
Profile  Provider.

Steps to reproduce

N/A

Proposed resolution

Ideally I would like an option in the module config to allow for the Instance Profile Provider to be used. By either allowing the user to select a "provider type" when creating a profile or by automatically detecting if there is an Instance Profile available and using that as the default (notifying the user when an Instance Profile is available).

Remaining tasks

User interface changes

API changes

Data model changes
