Make DPM.isActivePasswordSufficient() synchronous again
At the moment isActivePasswordSufficient() can return stale result
immediately after a password change since the latest password metrics
information is pushed from LSS to DPMS asynchronously (this is to
avoid deadlock between LSS and DPMS due to lock inversion). Fix this
by moving the password metrics ground truth to LSS, and make DPMS
query LSS about the password metrics when needed.
