feature(clone): add protocol option to force cloning over HTTPS
This is a rather quick and simple implementation to override the current logic and force clone with https. Allowing to explicitly clone over HTTPS is currently required to unblock reproducible builds where no ssh keys and GitLab user accounts are set up as of now. Hence this quick solution comes into play to mitigate the regression on reproducible builds builders.
Revisit the overall auto detection and protocol logic approach for a later release related to some ideas floating around in pending merge-requests.
