Checkmk Werk 13568: agent_azure: Enable passing secret via commandline (for debugging)

ID: 13568 Title: agent_azure: Enable passing secret via commandline (for debugging) Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Secrets for the special agents *should* be passed via stdin due to security reasons. But for debugging on the command line, we should enable passing them via a parameter. This was not working for agent_azure and is fixed now.
