Cloudfare module

[shelajev]

this PR adds a Cloudflare module to programmatically use Cloudflare Quick tunnels for exposing your app to the internet.

The use cases are:

• making your app available to hooks from public cloud.
• showing your local application to other people with ease.

Creating the cloudflared container and exposing a port on the host machine is now just a few lines of code away.

I think this is an unrelated failure now: https://github.com/testcontainers/testcontainers-java/actions/runs/8004718674/job/21862660520#step:4:1624

but I'm not sure :)
