execute_ipa_commands executes IPA API commands from the given command
list. With the handle_result and handle_result_user_args it is possible
to have a handling of the result return by the ipa commands for example
to return passwords.

Parameters

    commands: list of string tuple
        The list of commands in the form (name, command and args)
        For commands that do not require a 'name', None needs be
        used.
    handle_result: function
        The user function to handle results of the single commands
    handle_result_user_args: dict (user args mapping)
        The user args to pass to handle_result function

Example (ipauser module)

    def handle_result(result, command, name, args, exit_args):
        if "random" in args and command in ["user_add", "user_mod"] \
           and "randompassword" in result["result"]:
            exit_args.setdefault(name, {})["randompassword"] = \
                result["result"]["randompassword"]

    exit_args = {}
    changed = module.execute_ipa_commands(commands, handle_result,
                                          exit_args=exit_args)

    if len(names) == 1:
        ansible_module.exit_json(changed=changed,
                                 user=exit_args[names[0]])
    else:
        ansible_module.exit_json(changed=changed, user=exit_args)
