Two mqtt libraries

I've been contacted by my friend and sometime collaborator Takatoshi 
Kondo regarding his submission of a boost library: 
https://github.com/redboltz/async_mqtt. It has received two 
endorsements. He has asked me to be review manager and I'm inclined to 
accept this request as he was very helpful to me during the refinement 
of the boost serialization library.

There is also mqtt client library that is proposed to the Boost.
https://github.com/mireo/async-mqtt5 It also has endorsements and a 
review manager.

A cursory examination of the git hub pages suggest considerable overlap 
between the two submissions.  In general, boost has discouraged the 
acceptance of multiple libraries with this much overlap - and for good 
reason.  An accepted library often becomes the canonical implementation 
in large parts of the C++ world.  Having two high quality libraries that 
do almost the same thing is not where we would like to be.

I would like to propose that we review both libraries simultaneously in 
order to try to reach a consensus as to which, if either we want to 
accept.  I know this is a difficult task, but I think it is important 
that we do this.  It's going to be tough to reject a well written 
library because a better one has been accepted.  But it would be worse 
to reject a well written library merely because another one was 
submitted first.  Normally I don't participate as a review manager as 
I'm pretty bogged down in Boost stuff as it is.  But I'm willing to make 
an exception in this case due to the importance of this case and my 
strong personal ties to Takatoshi.  BTW - who is the review wizard these 
days?  I presume that he will be the one making the decision about this.
