What

• move the ios security template app from Feedhenry github org to AeroGear github org
• Update the description and the app name to be the AeroGear ios example app
• merge the functions from the current example apps and the security template apps into this new app (there might be new functions in the example app like push)
• make sure the new app can be used for both development and release demo, based on the results from the spike AEROGEAR-2507
• if possible, delete the example app from the SDK repo, and add links to the new showcase app.
