Add curl in alpine image
What does this MR do?
Add cURL library in the runner alpine image
Why was this MR needed?
In order to add the support of interactive web terminal in the Helm Chart project, the cURL program is needed to interact with K8s REST API.
Unfortunately, cURL program is not available by default in the runner alpine image and the wget program available by default doesn't support certificate to make the API calls.

What's the best way to test this MR?
