Add the base microversions test part
This is base part of microversions tests.
This patch adds the mechanism for selecting the microversion tests based
on new configration options like the following:
TestClass A: min_microversion = None, max_microversion = 'latest'
TestClass B: min_microversion = None, max_microversion = '2.2'
TestClass C: min_microversion = '2.3', max_microversion = 'latest'
TestClass D: min_microversion = '2.5', max_microversion = '2.10'
+--------------------+-----------------------------------------------------+
| Configration | Test classes |
| (min, max) | (Passed microversion) |
+====================+=====================================================+
| None, None | A(Not passed), B(Not passed), C & D - Skipped |
+--------------------+-----------------------------------------------------+
| None, '2.3' | A(Not passed), B(Not passed), C('2.3'), D - Skipped |
+--------------------+-----------------------------------------------------+
| '2.2', 'latest' | A('2.2'), B('2.2'), C('2.3'), D('2.5') |
+--------------------+-----------------------------------------------------+
| '2.2', '2.3' | A('2.2'), B('2.2'), C('2.3'), D - Skipped |
+--------------------+-----------------------------------------------------+
| '2.10', '2.10' | A('2.10'), B - Skipped, C('2.10'), D('2.10') |
+--------------------+-----------------------------------------------------+
| None, 'latest' | A(Not passed), B(Not passed), C('2.3'), D('2.5') |
+--------------------+-----------------------------------------------------+
| 'latest', 'latest' | A('latest'), B - Skipped, C('latest'), D - Skipped |
+--------------------+-----------------------------------------------------+
After this patch, we need to add tests for each microversion and
these test classes need to contain the range of microversions.
