openstack-config --set命令

`openstack-config --set` 命令用于设置 OpenStack 配置文件中的选项值。具体使用方法如下：

openstack-config --set /path/to/config-file section option value

其中，`/path/to/config-file` 是配置文件的路径；`section` 是配置文件中的节名；`option` 是需要设置的选项名；`value` 是需要设置的选项值。

例如，如果需要在 `nova.conf` 配置文件中将 `verbose` 选项的值设置为 `True`，可以使用以下命令：

openstack-config --set /etc/nova/nova.conf DEFAULT verbose True

这样就会将 `nova.conf` 文件中 `[DEFAULT]` 节下的 `verbose` 选项的值设置为 `True`。

优化下面代码：def watcher_maintenance_config(target_status): """The Watcher supports set system maintenance mode. Stop audits execution while set system maintenance mode, resume audits execution while unset system maintenance mode. """ # Check the node is master host first then check exists # openstack-watcher-api service. is_master = is_master_host() is_active = is_watcher_api_active() if not (is_master and is_active): logger("Ignore %s system maintenance mode on the node which is not " "master or watcher api is not started on." % target_status) return False return execute(target_status)

下面是优化后的代码：

def watcher_maintenance_config(target_status):
    """The Watcher supports set system maintenance mode.

    Stop audits execution while set system maintenance mode, resume audits
    execution while unset system maintenance mode.
    """
    # Check the node is master host first then check exists
    # openstack-watcher-api service.
    if not (is_master_host() and is_watcher_api_active()):
        logger("Ignore %s system maintenance mode on the node which is not "
               "master or watcher api is not started on." % target_status)
        return False
    return execute(target_status)

在优化后的代码中，我将 `is_master_host()` 和 `is_watcher_api_active()` 的结果直接用于判断条件，避免了多次函数调用。这样可以提高代码的效率。
