Downdetector parser

[hrichiksite]

Invoke by: !downdetector service-name

Example Invocation: !down detector aws
This would result in a link formation of https://downdetector.com/search/?q=aws, when clicked would redirect to https://downdetector.com/status/aws-amazon-web-services.

More work such as mapping a few well-known services to their pages is planned.

The code in the initial commits is used as base, more work is pending.

Note: Downdetector.com focuses on providers from the USA.
