Verify CocoaPods

[teobugslayer]

See #1294

How it works:

• install iOS runtime into a temporary directory
• create a simple Podfile into the template project
• run (sandobox-)pod
• verify nothing breaks

hm, why should we create new project, add platform and verify pod install command after that. Do we want to validate that project with pods can be created or that pods are useful on the machine?
I prefer to create Podfile in a temp dir and call pod install. Could this be done or we need some files from the runtime?

[teobugslayer]

Well, CocoaPods need a Xcode project to work on and that was the easiest way I could think of creating one.

We can print dots while waiting for pod install (we have a method in helpers that does this :) )

@rosen-vladimirov, without existing {N} project, CocoaPods complains with [!] Could not automatically select an Xcode project.

Can we mock it - for example we can add one default proj file in our resources, copy it to temp folder, create Podfile there and call pod install
There are many, many reasons why tns create app1 && tns platform add ios may fail and it will break doctor command. Do we want this?

[rosen-vladimirov]

maybe we should try-catch this one as well. As we know - npm fails sometimes and in this case our doctor command will fail
