upcoming Robot OS uploads to drop python2 support

[Sandro Tosi]

Hello folks,
in the next couple of days i will go thru all ROS packages to drop
their python2 packages; none of them has reverse dependencies in
Debian, and it will help greatly the effort described at
https://wiki.debian.org/Python/2Removal .

I'll commit my changes to their git repos but i'd like to upload
directly to unstable; please let me know if that's not ok and i'll
have you review the changes (which are usually very minimal and only
in debian/{control,rules}).

I know it's short notice, so apologies for that.

Cheers,
