Add 'net-tools' package dependency

Noticed this on a freshly installed, minimal Fedora-21 (from
development repos):

  $ ./stack.sh
  [. . .]
  2014-11-13 10:56:22.442 | + local exitcode=0
  2014-11-13 10:56:22.453 | + sudo route add -net 10.1.0.0/24 gw 172.24.4.2
  2014-11-13 10:56:22.479 | sudo: route: command not found
  2014-11-13 10:56:22.488 | + exit_trap
  [. . .]

Also added it to files/rpms-suse/general, just in case.

further pypi libs conversions

glance_store and saharaclient were missed in the last round, make
them install from released clients in this patch.
