Add test-os.sh utility to simplify run of kitchen tests for an OS

The script is able to search for all the test suites defined
into the functional cookbook and run them sequentially.

It must be executed from the root folder of the cookbook repo:
bash util/test-os.sh ec2 rhel8

The output will be saved into a `/tmp/kitchen-<os>-<date>` folder.

To run config tests is required to set a KITCHEN_${os}_AMI environment variable (e.g. KITCHEN_RHEL8_AMI)
or have a ParallelCluster AMI in the account.
