Run salt.minion.ca before salt.minion.cert

Make possible to generate certificates at the first run
of the script master_config.sh without re-tries.

Related-Bug: https://mirantis.jira.com/browse/PROD-21179

Also, some improvements for idempotency:
- wait for salt-master and salt-minion, using test.ping
- do not fail the script if all formulas are already symlinked
