Why I did it
In some cases , when downlink and uplink interfaces of isc-dhcp relay are configured with the same vrf(user configured, non-default vrf), dhcp relay will funcion abnormally.
Work item tracking
How I did it
Let dhcrelay process run in the vrf user configured. For the time being, it is supported only in IPV4 scenario. Supporting of IPV6 may be optimized later.
How to verify it
Config downlink and uplink interfaces of dhcp relay to the same vrf (default or non-default)，IPV4 dhcp relay shall work properly.
