Remove the requirement of carrying args in entry.exit()

[LiYangSir]

Describe what this PR does / why we need it

Remove the requirement of carrying args or batchCount in entry.exit() so that users don't need to carry args or batchCount on Entry exit.

Does this pull request fix one issue?

Fixes #3109

Describe how you did it

Hold args and batchCount in Entry when initialized, when calling the no-argument exit() method, use the hold data

Describe how to verify it

Use unit test to verify the correctness of totalSuccess() method

@Test
public void testEntryExitAutomation() throws BlockException{
    String[] args = {"foo", "baz"};
    int batchCount = 3;
    Entry e = SphU.entry("resourceName", EntryType.IN, 3, args);
    e.exit();
    assertEquals(batchCount, e.getCurNode().totalSuccess());
}
