Add manifest service attribute foregroundServiceType

Foreground service must use attribute foregroundServiceType to
specify its foreground service type in <sevice> element of manifest
file, otherwise a warning message is printed when startForeground()
method is called. (We will replace the warning message with a security
exception when the feature is formally activiated.)
The manifest attribute is:
android:foregroundServiceType="<type>"

Allowed types are: "sync", "mediaPlay", "phoneCall",
"location", "deviceCompanion", "ongoingProcess".
