Describe the bug:
If calling spk project install-lifecycle-pipeline with a --repo-url that is missing a the http(s) protocol we give the non-informative error:

Error occurred installing pipeline for project hld lifecycle.
Could not determine origin repository, or it is not a supported type.

This situation can be seen here.

Expected behavior:
We should have clear error messages. We should use the techniques described here to have an error message that says the --repo-url is malformed.

Does this require updates to documentation?:
Probably
