HDDS-9978. Improve assertTrue assertions in OM integration tests

[wzhallright]

What changes were proposed in this pull request?

Improve assertTrue assertions in hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/ozone/om
Assertions in the form:

assertTrue(<string>.contains(...))

do not provide any information about the actual value, if the assertion fails.

AssertionFailedError: expected: <true> but was: <false>

This can be improved by replacing them with:

import static org.assertj.core.api.Assertions.assertThat;
assertThat(<string>).contains(...)

which gives us more info in the form:

AssertionError: 

Expecting:
 <"actual string">
to contain:
 <"part"> 

Similarly, assertions about inequality relations, e.g.:

assertTrue(<x> > <y>)

can be replaced with:

assertThat(<x>).isGreaterThan(<y>);

The goal of this task is to find and replace such assertTrue assertions.

@wzhallright, I think you have to wait for HDDS-9922 and update https://github.com/apache/ozone/pull/5838/files?diff=unified&w=0#diff-7204a4e31ff9ef05e7839a26737265513d5aedc6ddeac72a9cbda7f263a0ddffR1826 as well.

OK,Thanks for review @hemantk-12. I will rebase and update it after #5838 is merged.

[adoroszlai]

No need to wait/rebase, filesystem integration tests will be covered by separate sub-task later.

Thanks @wzhallright for the improvement.
