Calling APIs with AK/SK in Non-configuration Mode

Add the --cli-access-key, --cli-secret-key, and --cli-security-token options in a command to call a cloud service API with an AK/SK in non-configuration mode.

By default, if only --cli-access-key and --cli-secret-key are used in a command, the AK/SK are taken as permanent ones.
