86a13610cb [docker-fpm-frr]: TSA/B/C changes for multi-asic (#6510)
- Introduced TS common file in docker as well and moved common functions.
- TSA/B/C scripts run only in BGP instances for front end ASICs.
       In addition skip enforcing it on route maps used between internal BGP sessions.

admin@str--acs-1:~$ sudo /usr/bin/TSA
System Mode: Normal -> Maintenance

and in case of Multi-ASIC
admin@str--acs-1:~$ sudo /usr/bin/TSA
BGP0 : System Mode: Normal -> Maintenance
BGP1 : System Mode: Normal -> Maintenance
BGP2 : System Mode: Normal -> Maintenance

beaaf3316d [docker-frr]: Use egrep with regexp to match correct TSA rules (#6403)
**- Why I did it**
Earlier today we found a bug in the SONiC TSA implementation.
TSC shows incorrect output (see below) in case we have a route-map which contains TSA route-map as a prefix.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Not consistent
```
The reason is that TSC implementation has too loose regexps in TSA utilities, which match wrong route-map entries:
For example, current TSC matches following
```
route-map TO_BGP_PEER_V4 permit 200
route-map TO_BGP_PEER_V6 permit 200
```
But it should match only
```
route-map TO_BGP_PEER_V4 permit 20
route-map TO_BGP_PEER_V4 deny 30
route-map TO_BGP_PEER_V6 permit 20
route-map TO_BGP_PEER_V6 deny 30
```

**- How I did it**
I fixed it by using egrep with `^` and `$` regexp markers which match begin and end of the line.

**- How to verify it**
1. Add follwing entry to FRR config:
```
str-s6100-acs-1# 
str-s6100-acs-1# conf t
str-s6100-acs-1(config)# route-map TO_BGP_PEER_V4 permit 200 
str-s6100-acs-1(config-route-map)# end
```
2. Use the TSC command and check output. It should show normal.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Normal```

f4245fb18d [bgpcfgd]: Support default action for "Allow prefix" feature (#6370)
* Use 20 and 30 route-map entries instead of 2 and 3 for TSA

* Added support for dynamic "Allow list" default action.

2f44bcd071 [bgpcfgd]: Split one bgp mega-template to chunks. (#4143)
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
