[SPARK-10790][YARN] Fix initial executor number not set issue and
consolidate the codes
This bug is introduced in
[SPARK-9092](https://issues.apache.org/jira/browse/SPARK-9092),
`targetExecutorNumber` should use `minExecutors` if `initialExecutors` is not
set. Using 0 instead will meet the problem as mentioned in
[SPARK-10790](https://issues.apache.org/jira/browse/SPARK-10790).
Also consolidate and simplify some similar code snippets to keep the
consistent semantics.
