update weather package documentation (#301)

1. Update vendor branding Bluemix ==> IBM Cloud
2. Update package binding instructions; IBM docs no longer
   recommend `package refresh`, so we can have uniform
   instructions to instantiate the package explicitly with
   username, password, and host info.
