SAMZA-1176: Intermittent TestJoinOperator unit test failure
Join TTL was set too low (10 ms). `joinRetainsMatchedMessagesReverse` will
fail if the execution time between line 176 and 186 is longer than that.
Increased TTL to 1 min (will not affect test execution time).

> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Prateek Maheshwari
> Assignee: Prateek Maheshwari
> Fix For: 0.13.0
>
>
> There are occasional failures like the following:
> ```joinRetainsMatchedMessagesReverse FAILED
> java.lang.AssertionError: expected:<0> but was:<110>
> at org.junit.Assert.fail(Assert.java:91)
> at org.junit.Assert.failNotEquals(Assert.java:645)
> at org.junit.Assert.assertEquals(Assert.java:126)
> at org.junit.Assert.assertEquals(Assert.java:470)
> at org.junit.Assert.assertEquals(Assert.java:454)
> at
> org.apache.samza.operators.TestJoinOperator.joinRetainsMatchedMessagesReverse(TestJoinOperator.java:174)```
> These are presumably due to concurrent JUnit test execution. This ticket is
> to isolate these test cases so that they can be run concurrently.
