- fix access to addr_method on an object which had no
address method defined. This was a recently introduced
regression that caused vrf enslavement to end per-matuarely.

Testing Done: Tested vrf enslave/deslave + ifreload
This patch fixes a few corner cases:
- release dhcp on all new enslavement or change of enslavement
- fix a NoneType error on ifreload when a vrf enslavement was removed
- handle a corner case with auto table ids

algo:
- when a vrf slave enslavement changes, before performing the
new master enslavement,
- check if vrf slave has dhcp configured
- if yes, release dhclient running on the vrf slave

Testing Done: Tested with table id auto for management vrf
I have recently added special handling for vrf slaves with dhcp.
And missed handling of vrf-table auto for such slaves.
This patch fixes auto when bringing up vrf masters for dhcp vrf
slaves

Testing Done: tested with vrf slaves with dhcp
Problem:
since vrf slaves are brought up before master, When vrf slaves are
configured for dhcp, the dhclient hook for vrf runs before the master is
up. This was seen with management vrf.
This solution is special logic to handle vrf slaves with
dhcp in the vrf addon module.
currently only supports interface declared with dhcp and
indicated as vrf slave. as in example below (dhcp and vrf must be in the
same iface stanza):
auto eth0
iface eth0 inet dhcp
vrf mgmt
changes to vrf module:
- make vrf module methods accept the ifaceobj lookup function, which is
already passed as argument to all methods from ifupdown scheduler
- during vrf slave bringup,
- if master does not exist and slave's address_method is dhcp
- lookup master object, and bring up the vrf master
- mark this master as processed so that the next time this vrf
module sees master it knows that it is already processed
(this is covered by the vrfPrivFlags)

This was causing vrf enslavement errors during bootup.

This patch checks if fib rule for local table have higher pref
than vrf table, if not, it deletes fib rule for local table
with lower pref and adds fib rule for local table with
higher pref than vrf table.

This patch adds a check to detect change in vrf config table id
compared to running table id and throw an error accordingly.
The vrf device may not be up when ifup is executed on the
slaves. This commit makes sure:
- vrf slaves dont try to enslave themselves when vrf device is
not present
- And vrf master enslaves any missing slaves during ifup of vrf master
- Also make vrf device the link master, this will make sure
the vrf device brings the vrf slave links up. This is needed to work
around the ipv6 address flush issue

This patch adds per vrf default route: "ip route add table <tbid> unreachable default"
It also accepts a policy file with vrf-default-route [yes/no]
This also includes ifquery fixes for running and check.
This patch adds initial support for vrf in ifupdown2.
Example interfaces file section:
auto swp1.100
iface swp1.100
vrf blue
auto blue
iface blue
vrf-table 10
iproute2 vrf map is generated under:
/etc/iproute2/rt_tables.d/ifupdown2.vrf_map
this patch also adds prelimnary support for 'vrf-table auto'.
But this needs more work.
