Feature request: Support nested suites

[Bolodya1997]

Issue

Junit 5 supports nested tests so it possibly can result in nested <testsuite> tags in xml output:

<testsuites>
    <testsuite tests="4" failures="0" time="150.0" name="All tests">
        <testsuite tests="2" failures="0" time="30.0" name="TestA">
            <properties></properties>
            <testcase classname="" name="A" time="10.0" cluster_instance="packet-1">
                <failure message="failure"></failure>
            </testcase>
            <testcase classname="" name="B" time="20.0" cluster_instance="packet-1"></testcase>
        </testsuite>
        <testsuite tests="2" failures="1" time="70.0" name="TestB">
            <properties></properties>
            <testcase classname="" name="A" time="30.0" cluster_instance="packet-1"></testcase>
            <testcase classname="" name="B" time="40.0" cluster_instance="packet-1">
                <failure message="failure"></failure>
            </testcase>
        </testsuite>
        <testcase classname="" name="A" time="50.0" cluster_instance="packet-1">
            <failure message="failure"></failure>
        </testcase>
    </testsuite>
</testsuites>

Currently action-junit-report doesn't support nested suites and looks up only for first level depth <testcase> tags in the root test suites.

Solution

1. Add recursive parsing for the nested test suites.
2. Add suite_regex parameter, so nested test cases would be reported not as A, B, but as TestA/A, TestA/B.
