Flashes used for the 7050QX-32 and 7050QX-32S have a fw issue.
The best option to solve the problem is to upgrade to a newer firmware.
However this can only be done while in memory and take 10 seconds.
Adding an upgrade mechanism is possible but would need more
consideration as flashing the firmware and reformating the flash will
exceed the fast-reboot requirements.

A quick mitigation is to align the ext4 partition that we create on
these vfat based system on a 4k boundary.
Here we chose 1M instead but it's the same.
Newer version of sfdisk do this automatically but the one in SONiC
today doesn't have this behavior.

This workaround will only reduce the pace of the flash health
degradation. The only long term fix is to flash the firmware.

* FRR 4.0 integration with SONiC

-- Uses SONiC FRR repo frr/4.0 (which has SONiC support) to build image
-- Makefile changes to make frr4.0 builtable.
-- Updated/Added FRR configuration files
-- bgpd jinja template fixes

To build SONiC images with FRR4.0, simply edit rules/config file and change
routing stack to following:

SONIC_ROUTING_STACK = frr

and then build images as usual.

* Used integrated-vtysh-config in FRR
Changed to single template: frr.conf.j2 for configuration and added tests
