vyos.util: T4575: Add new wrapper "rc_cmd"
It is useful to have both a return code and output of the command
Add a new wrapper "rc_cmd" that returns both
% rc_cmd('uname')
(0, 'Linux')
% rc_cmd('ip link show dev fake')
(1, 'Device "fake" does not exist.')
(cherry picked from commit 14418b6d80ef4652a44d9280baf369c8e3c429fd)
