Change-Id: I6145ebde8dfa1fd28a69fbc8e9f6024dd1f94ae6
Added password length req, moved Sensor Handler

Added 8-character password length requirement to match new user
model that is implemented in svmp-server.
Moved Sensor Handler out of AppRTC Client (which is a binder object
that should only contain objects/properties that need to be shared
between the service and activity), into the Session Service.
