devtool: show some warnings for upgrade versions

* Show a warning in devtool upgrade if the version is less than the
  current version suggesting that the user may need to bump PE in the
  recipe
* Show a warning in devtool add and devtool upgrade if the version looks
  like a pre-release version suggesting using a version number that
  won't mess up the progression when you come to upgrade to the final
  release version.
