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.
The one big bgp configuration template was splitted into chunks.
Currently we have three types of bgp neighbor peers:
general bgp peers. They are represented by CONFIG_DB::BGP_NEIGHBOR table entries
dynamic bgp peers. They are represented by CONFIG_DB::BGP_PEER_RANGE table entries
monitors bgp peers. They are represented by CONFIG_DB::BGP_MONITORS table entries
This PR introduces three templates for each peer type:
bgp policies: represent policieas that will be applied to the bgp peer-group (ip prefix-lists, route-maps, etc)
bgp peer-group: represent bgp peer group which has common configuration for the bgp peer type and uses bgp routing policy from the previous item
bgp peer-group instance: represent bgp configuration, which will be used to instatiate a bgp peer-group for the bgp peer-type. Usually this one is simple, consist of the referral to the bgp peer-group, bgp peer description and bgp peer ip address.
This PR redefined constant.yml file. Now this file has a setting for to use or don't use bgp_neighbor metadata. This file has more parameters for now, which are not used. They will be used in the next iteration of bgpcfgd.
Currently all tests have been disabled. I'm going to create next PR with the tests right after this PR is merged.
I'm going to introduce better bgpcfgd in a short time. It will include support of dynamic changes for the templates.
FIX:: #4231
* start bgp_eoiu_mark service to populate bgp eoiu marker if configured so
* Address code review comments: check db value via "-v" option in sonic-cfggen
* Address code review comment 2: check string against 'true' directly, instead of couting
* Update start.sh
* Rename asn/deployment_id_asn_map.yaml to constants/constants.yaml
* Fix bgp templates
* Add community for loopback when bgpd is isolated
* Use correct community value
Now it's possible to add and remove peers based on ConfigDB
- What I did
Fixed functionality for dynamically adding/removing static bgp peers.
- How I did it
Split the bgp default template on bgp part and bgp peer part
Changed bgpcfgd to use 1.
- How to verify it
Build an image and run on your DUT
The owner of the generated files (/etc/frr/*.conf) by start.sh is root if it is a new file.
This will cause error when executing "copy running-config startup-config" in vtysh because of privilege issue.

- Extending SONiC building infrastructure to provide users
with greater flexibility, by allowing them to elect a
routing-stack different than the default one (quagga). The desired
routing-stack will be defined in rules/config file.
- As part of these changes I'm adding support for
Free-Range-Routing (FRR) stack. Quagga will continue to be
the default routing-stack.
