Bug: import when path is a (http/https) url does not allow renaming

[smoser]

stacker version

v1.0.0-rc4-8e267fc

Describe the bug

stacker cannot rename an import when the 'path' is a http or https url. the imported path will be the basename of the url.

To reproduce

1. Configuration stacker.yaml

   
   build:
   build_only: true
   from: 
   type: docker
   url: ${{DOCKER_BASE:docker://docker.io/library}}/busybox
   import:
   - path: /etc/passwd
     dest: /imports/host-file
   - path: https://www.cisco.com/favicon.ico
     dest: /imports/http-file
   run: |
   #!/bin/sh
   set +e
   
   ERRS=0
   err() { echo "$@"; ERRS=$((ERRS+1)); }
   assertFile() {
     [ -f "$1" ] || {
       err "$1: not a file"
       return 1
     }
     return 0
   }
   
   ls -l /imports
   assertFile /imports/host-file
   assertFile /imports/http-file
   
   [ "$ERRS" = "0" ]
