Comment 11 for bug 1393505

I'll going to continue work on this bug at next week.
Firstly I decide to check different rpc service executors in oslo.messaging library in MOS 6.x. Now in ceilometer messaging we use eventlet executor but also 'thread' and 'blocking' executors are available. We'll test performance and correct work for these executors and update bug status with results.
For MOS 5.1 relative aspects will be researched.
