This patch breaks introduces a helper function in cozy-lib to correctly
handle special case resources when transforming a nested map of limits
and requests to a flat map suitable for use in resourceQuotas. As a
result, admins can now specify any types of resources as resource quotas
for tenants, and they will be correctly transformed to the correct
format for the underlying kubernetes ResourceQuota. In addition to the
previously supported compute resources, such as CPU, memory, and custom
resources, like GPUs, special quota strings such as
"services.loadbalancers" are now correctly handled.
```release-note
[cozy-lib,platform] Support resource quotas for special kubernetes
quotas, such as service.loadbalncer count and others.

## What this PR does
The cozy-lib library package got complicated enough to warrant its own
unit tests. Since unit tests are a "good thing" (tm), a somewhat generic
framework for running all kinds of unit tests was introduced into the CI
pipeline and Makefile targets. For now all it runs is `make test`
against the `packages/{library,apps,system,extra}/*` directories,
wherever a `test` target is present in the Makefile, and for now this is
only for the `cozy-lib` Helm library chart.
### Release note
```release-note
[ci,dx] Introduce a scaffold for running unit tests locally and in CI
and add the first unit tests for the cozy-lib helper Helm chart.
