Description

Now, for Flink on YARN deployment mode, each am's vcores is specified to 1 (hard code).

In some scene, we found many Akka timeout logs, the Flink web UI cannot be opened, but it is alive. I think there is no more threads resource to be used for am. So we suggest that make the vcores num of application master can be configurable.
