Component:

'salt', 'tests'

Why this is needed:

Currently, we do not test python function from our utils modules

What should be done:

Tests all function from all our custom utils modules with 100% coverage, run in pre-merge and with tox in unit-tests

NOTE: Here the list of utils modules, that may (or may not) be split in different issues

• kubernetes_utils (Add unit test for metalk8s_kubernetes module #2041)
• pillar_utils
• volume_utils
• metalk8s_utils (2.6+)

Implementation proposal (strongly recommended):

Same as for #2266 check in salt/tests/unit/modules
