The following should get you what your asking for, if I understand you
correctly:

git clone --recursive -b develop https://github.com/boostorg/boost

git submodule foreach git checkout develop

Now I'm not sure that's what you need.  You will get the latest changes
from each of the repositories, but what are the entrance criteria for
adding something to develop or master?  Does it have to compile?  Do all
the changes have unit-tests that pass?

I would assume the criteria for master would be more strict that develop,
e.g. all changes on develop for a repository have to build with the latest
changes on all the other repositories while changes on master have to also
pass all their unit-tests.
