This is part of the work to unify the manual certificate
installation flow (via "Install from storage" in the Settings
app) with the programmatic one (using
DevicePolicyManager.installKeyPair).
The change to CredentialStorage is the crux of this work, where
the key is no longer installed by calling Keystore directly.
Instead, a new AsyncTask, InstallKeyInKeyChain, was created, which
calls KeyChainService.installKeyPair with the key data and associated
certificates (as well as the UID of the designated service, to allow
installation into the WiFi Keystore).
Once that task completes, if the key was installed successfully,
then it is marked as user-selectable.

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.
