See https://github.com/apache/incubator-openwhisk-cli/blob/master/commands/api.go#L916

Instead of hardcoding the protocol to https use the protocol configured in the apihost

I submitted PR 2909 for this.

I just got bit by this today when trying to use wsk api create with a .wskprops that was "misconfigured" to have APIHOST=https://MY_HOST instead of APIHOST=MY_HOST. The symptom was that invoking the resulting APIs gave a 502 (bad gateway) because the created actions were given the url https://https://MY_HOST/
