Add support for Aio refreshable creds for assume role

[pankajkoti]

Currently, for assume_role method, the hook gets a one time credentials
and when they expire the sensor fails. Thus, we leverage refreshable
credentials to support the sensor and not fail when using assume_role
method with the role_arn type connections.

closes: #1292

[pankajkoti]

Verified that credentials get refreshed by having added some temporary logs and tweaking around expiration.

will work next on tests

LGTM.

1. we should test the existing aws integration test on Astro once
2. what do you think about adding an integration test or using some existing one to use this method of authentication?

1. I tested existing AWS integration locally on runtime image without the role_arn i.e. existing AWS integration and it runs fine too.
2. Yes perhaps, we can use the same example DAG with a different connection using role_arn. Will create a follow-up PR for this.
