setup and teardown Application & Director(y|ies) rather than relying on STORMPATH_APPLICATION_HREF

[dogeared]

All setup an config should be handled by the TCK. The only upfront config requirements should be setting the api key id and secret, either from ~/.stormpath/apiKey.properties, STORMPATH_API_KEY_FILE are valid env files.

The TCK can create an Application and associated Directory and use that for all the tests.

This will also help with different modes we want to support, like enabling email verification workflows.
