provided in the bug (app-debug.apk)

Currently the code assumes that the user always has a pin or
password or pattern. If there's no password confirmKeyGuard() will
return false, so the acttivity will finish without doing anything.
With this change if there's no PIN/password/pattern, the credential
clearing task will be launched straightaway as the user presses "OK"
the confirmation prompt.

Additional clean-up work related to removal of screenlock dependency
from the credentials installation flow:
* Move the CredentialStorage class to security/ so that Enterprise team
owners could review changes to it.
* Remove the ConfigureKeyGuardDialog class as it is no longer used.
* Remove attempt to unlock KeyStore from VPN settings.
* Remove intents that will no longer be sent from the manifest.
