- Why I did it
The values for config_db "docker_routing_config_mode" are:
separated: FRR config generated from ConfigDB, each FRR daemon has its own config file
unified: FRR config generated from ConfigDB, single FRR config file
split: FRR config not generated from ConfigDB, each FRR daemon has its own config file
This commit adds:
split-unified: FRR config not generated from ConfigDB, single FRR config file
- How I did it
In docker_init.sh, when split-unified is used, the FRR configs are not generated
from ConfigDB. What's more, "service integrated-vtysh-config" is configured in vtysh.conf.
- How to verify it
FRR config not overwritten when FRR container starts.

For the split mode, the config files, like bgpd.conf, zebra.conf and so on, were provided by outside. But the docker_init.sh will overwrite the outside config files if restart bgp service.
How I did it
Add a split mode checking in docker_init.sh, if docker_routing_config_mode is split, don't overwrite the existing routing config files.
How to verify it
Set split mode in config db
{
"DEVICE_METADATA": {
"localhost": {
"hwsku": "Force10-S6000",
"platform": "x86_64-kvm_x86_64-r0",
"docker_routing_config_mode": "split"
...
}
}
}
Replace your bgpd.conf to /etc/sonic/frr/bgpd.conf
Restart bgp service by sudo service bgp restart
The /etc/sonic/frr/bgpd.conf your provided shouldn't be overwritten

- Support for non-template based FRR configurations (BGP, route-map, OSPF, static route..etc) using config DB schema.
- Support for save & restore - Jinja template based config-DB data read and apply to FRR during startup
**- How I did it**
- add frrcfgd service
- when frr_mgmg_framework_config is set, frrcfgd starts in bgp container
- when user changed the BGP or other related table entries in config DB, frrcfgd will run corresponding VTYSH commands to program on FRR.
- add jinja template to generate FRR config file to be used by FRR daemons while bgp container restarted
**- How to verify it**
1. Add/delete data on config DB and then run VTYSH "show running-config" command to check if FRR configuration changed.
1. Restart bgp container and check if generated FRR config file is correct and run VTYSH "show running-config" command to check if FRR configuration is consistent with attributes in config DB

**- Why I did it**
We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers
Calls to sonic-cfggen is CPU expensive. This PR reduces calls to
sonic-cfggen to two calls during startup when starting frr service.

* Changes to make default route programming
correct in multi-asic platform where frr is not running
in host namespace. Change is to set correct administrative distance.
Also make NAMESPACE* enviroment variable available for all dockers
so that it can be used when needed.

* Fix review comments
* Review comment to check to add default route
only if default route exist and delete is successful.
