05ac52f075 addons: vrf: redo iproute2 vrf interface map handling
Ticket: CM-10188, CM-10061
Reviewed By: dsa, nikhil, julien
Testing Done: Tested static routes with vrf names for tables

This patch does the following:
- if a single vrf device is present in the config,
builds the vrf map by reading vrf interfaces from the kernel (with
existing link cache. Builds a shadow vrf only attribute cache)
- reads existing table map and adjusts it if required
- main change is the iproute2 map file on disk is updated
immediately on vrf creation, so that static routes used along with the
vrf slaves can use the vrf name for the table. This also helps dhclient dns
hook script which may use mgmt table name directly.
- cleans up default routes on down

8ad5c76784 addons: vrf: special handling for vrf slaves configured for dhcp
Ticket: CM-9868
Reviewed By: dsa, nikhil, julien
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)
