Subject: Add template creation test, --skip-editor option (#11970)

* Add template creation test
* Added --skip-editor option to "spack create": normally
  "spack create" opens an editor for the user after generating a
  package file; when the --skip-editor option is used, "spack create"
  only generates the package file and does not open an editor
* Added --skip-editor option to bash completion
