Speedtest check

[ldrrp]

Problem

On occasion we want to check the speed of our internet connection to know if we are facing issues. I know its possible to do so via home assistant or openhub but some may not be using such systems.

Solution

Simple yaml config value to check the speed of the internet connection. Should have a min and expected value. and use notify similar to the other checks. User should be able to specify the cron interval. Check the users entered cron value for correcteness.
