[UX] AWS IoT integration configuration view

We need another view in the "Integration" settings view for setting up the integration with AWS IoT. In contrast to Azure, we will need as a minimum 3 inputs: The user access key id, access key secret, endpoint URL and a device policy ARN. Example values:

Access key ID: AKIAIOSFODNN7EXAMPLE

Access key secret: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

Endpoint URL: abcdefg123456.iot.us-east-1.amazonaws.com

Policy ARN: arn:aws:iam::123456789012:policy/MyIAMThingsPolicy

Some hints/tooltips for setting up the user could also be useful, but not strictly required (this will also be covered by the documentation).
