Add a dependency file for os-brick (and add lsscsi)

There are a few dependencies which are really os-brick-specific.
They are listed in its bindep.txt file, but os-brick is usually
installed from pip, so its bindep.txt file is not available.

As those dependencies are needed by the various services
which use os-brick, move them to their own dependency file
(with the addition of the new lsscsi, required by the next
os-brick stable release) and make sure that file is parsed
when installing the services which require os-brick.

Side note: there should be a way to avoid this duplication
also for pip-installed libraries (normal services can use
files/ or even bindep, but in this case the source is not always
available), (temporarily?) duplicate them, as it has been
the case for the other os-brick dependencies already listed here.
