yum search qpid gives you a hint what qpid is. I'm not familiar with it but the message seems to suggest you need to configure SSL certificates in qpid's configuration to enable secure SSL communication between qpid and its clients (of whatever they are called in the AMQP world).
If you don't use qpid then I guess you could remove it.
