8008368: Deprecate MaxGCMinorPauseMillis
https://jbs.oracle.com/bugs/browse/JDK-8008368

webrev:

changeset:
We don't need the distinction between MaxGCMinorPauseMillis and 
MaxGCPauseMillis. The MaxGCMinorPauseMillis flag was introduced as a 
backup measure in case one pause target for all types collections was 
not enough. As it has turned out it seems one pause target is enough. 
Thus, we should deprecate MaxGCMinorPauseMillis and give a warning when set.

testing:
passed JPRT test(sanity)
