Adding resizing to the FS.
Some background around the changes outside the FS:
# the {{RMContainerImpl}} logs a message when the temporary containers for
resizing are released because they are in the wrong state. The new transitions
clean those up
# Normalising requests has been moved from the {{CapacityScheduler}} into the
{{AbstractYarnScheduler}} as it is used by both schedulers.
# Resizing would only use the ANY request and leave node and rack requests
hanging around which caused the FS to allocate strange containers.
{{AppSchedulingInfo}} now allows for cleaning up the unneeded requests from the
{{ContainerUpdateContext}}
