Enabled the selection of cloudflare speedtest

[martinbrose]

Created a new Docker image called redorbluepill/cloudflare-speedtest-exporter to replace the current Ookla Speedtest Prometheus Exporter and enabled the selection of the speedtest images through a variable called monitoring_speedtest_provider in config.yml. Replacing the image in file internet-monitoring/docker-compose.yml is implemented with two localhost ansible.builtin.replace tasks. There might be a smarter way of doing this?

Fixes #341:

• #341

Looking forward to this!!

It might be easier to make that file a template and make it a configurable variable instead.

Ok, I think I messed up the rebase to the master branch. Will close this pull request and open a new one.
