[SPARK-19824][Core] Standalone master JSON not showing cores for running
applications
## What changes were proposed in this pull request?
This fix tries to address the issue raised in SPARK-19824 where
the JSON API of the standalone master ("/json") does not show
the number of cores for a running (active) application, which is
available on the master UI.
The reason was that in master UI, `coresGranted` was used:
https://github.com/apache/spark/blob/v2.1.0/core/src/main/scala/org/apache/spark/deploy/master/ui/MasterPage.scala#L220
while in JSON API, the `desc.maxCores` was used. In case
there is no limit on `maxCores`, this filed will be missing on
JSON API. (Master UI show cores granted so the field is always available).
This fix address the discrepancy by changing JSON API to use
`coredGranted` so that UI and JSON API are consistent.
## How was this patch tested?
The test was done manually.
