IMPALA-7148: Make test_profile_fragment_instances() more robust
test_profile_fragment_instances() makes assumption about number
of instances of each scan node in the distributed query plan.
The number of instances for each scan nodes can actually vary
depending on how data is loaded and scheduler's decision.
This change relaxes the check for number of instances of each
scan node is a multiple of 3 which is the number of scan nodes
in the plan.

> URL: https://issues.apache.org/jira/browse/IMPALA-7148
> Project: IMPALA
> Issue Type: Test
> Affects Versions: Impala 2.13.0, Impala 3.1.0
> Reporter: Thomas Tauber-Marshall
> Assignee: Thomas Tauber-Marshall
> Priority: Critical
> Fix For: Impala 3.2.0
>
>
> The underlying bug in IMPALA-6338 was causing a large number of flaky tests
> and was tricky to fix given our present coordinator runtime profile handling.
> We decided to temporarily disable these tests pending work on the coordinator
> (MPALA-2990/IMPALA-4063). Once that work is done, we should re-enable these
> tests.
> The tests have been re-enabled since IMPALA-4063 has been fixed. However,
> there seems to be some flakiness with some tests not related to IMPALA-4063
> or IMPALA-6338.
