Support offline drm key downloading and restoring 

Renamed StreamingDrmSessionManager to DefaultDrmSessionManager and added functionality to download, restore, renew and release offline keys. Added a utility class, OfflineLicenseHelper, to facilitate use of DefaultDrmSessionManager for downloading, renewing and releasing offline keys.
