> ContainerOperation Client creates XceiverClientManager.
> XceiverClientManager requires to getCA list.
> {code:java}
>       manager = new XceiverClientManager(conf,
>           conf.getObject(XceiverClientManager.ScmClientConfig.class),
>           caCertificates);
> {code}
> We can avoid listCA which is not required for most admin commands. It is required only for ChunkKeyHandler.
> This will help when ACLS are configured for SCM security protocol where only admin/service principals can make calls to the SCMSecurityProtocol server, then we don't need to add all the users to them to make these commands work.
> As for few of the commands like pipeline list, safe mode status we don't require admin privilege.
