vrf: T591: define sysctl setting for net.vrf.strict_mode
Enable/Disable VRF strict mode, when net.vrf.strict_mode=0 (default) it is
possible to associate multiple VRF devices to the same table. Conversely, when
net.vrf.strict_mode=1 a table can be associated to a single VRF device.
A VRF table can be used by the VyOS CLI only once (ensured by verify()), this
simply adds an additional Kernel safety net, but a requirement for IPv6 segment
routing headers.
(cherry picked from commit 10701108fecb36f7be7eb7ef5f1e54e63da5fb4e)
