CAIQUM-7114：在启用了CA签名证书和云代理的情况下、在AIQUM 9.14+中添加集群或监控失败

问题描述

• 如果AIQUM 9.14+在端口443上使用CA签名证书、在server.properties文件中启用了云代理、在9.14或更高版本中启用了ONTAP、则集群添加和收集将失败、并显示云代理连接错误
• 
  server_acq.log: 
ERROR [acq-facade-init-thread-ds-2] c.n.u.CloudAgentConnectionUtil (CloudAgentConnectionUtil.java:254) - Establishing connection with cluster <cluster_ip> failed

• 一旦AIQUM使用自签名证书、REST集合将继续有效
• 只有在AIQUM上使用CA签名的证书且为REST集合启用了云代理的情况下、才会显示问题描述
