Python 2 support was retained for use with --enable-python=system on RHEL7 and SLES. The time has arrived to remove it. Some .py files that were imported from third parties are not changed to enable easier replacement with updated versions if necessary. solenv/gdb should continue to support Python 2. bin/get-bugzilla-attachments-by-mimetype requires Python 2 to access Launchpad.
