DPM: Deprecate password quality-related methods

Deprecate setPasswordQuality and related methods, since:
* setRequiredPasswordComplexity is a suitable alternative for
  most cases.
* Password quality may not be applied to the parent profile anymore,
  to avoid personal data being tied to work-set lockscreen requirements.

Additionally, change the exception thrown when the profile owner calls
setPasswordQuality on the parent profile to be a SecurityException
rather than an IllegalArgumentException
