[DISCUSS] Release 1.5.5 and 1.6.2

[Chesnay Schepler]

Hello,

we've accumulated various fixes for 1.5.5 (24) and 1.6.2 (37) that 
improve stability by quite a bit along with some neat usability fixes.

I'm proposing to do the next bugfix releases soon (I suggest tomorrow as 
a tentative vote date), and volunteer to handle the release process for 
both of them.

There are some back-ports that I myself want to get in first 
(FLINK-10282, FLINK-10075, FLINK-10135) but this should be done by today.


Regards,

Chesnay
