CloudPolicyValidator now accpets a "domain" parameter which is used to generate
verification signatures for public keys.

Broke out CloudPolicyValidator cached-key verification code into a separate
validation function: ValidateCachedKey().

Added new hard-coded signatures for our PolicyBuilder test keys for the
example.com domain.
