Create the ResumeOnRebootService.

This is the base class for service that provides wrapping/unwrapping of the opaque blob needed for
ResumeOnReboot operation. The package needs to provide a wrap and unwrap
implementation for handling the opaque blob, that's secure even when on
device keystore and clock is compromised. This can be achieved by using
tamper-resistant hardware such as a secure element with a secure clock,
or using a remote server to store and retrieve data and manage timing.
