supervisor管理服務prometheus+alertmanager

說明：對于需要自啟動的服務用supervisor管理，可實作自啟動enable、status、start、stop等操作

# 安裝，所用系統為Ubuntu
apt-get install supervisor
vim /etc/supervisor/supervisord.conf
systemctl status supervisor.service 
systemctl restart supervisor.service
# 設定開機自啟
systemctl enable supervisor.service
           

修改配置檔案，添加管理子產品
