BGP SoO is a tag that is appended on BGP updates to allow a peer to mark
a particular peer as belonging to a particular site. In certain MPLS L3 VPN
configurations, the BGP AS-Path may not provide the granularity needed
prevent a loop in the control-plane. With this in mind, BGP SoO is designed
to fill this gap and prevent a routing loop that may occur.
If we configure for example, `neighbor soo 65000:1` at PEs, routes won't be
announced between CPEs if soo matches. This is especially needed when using
as-override or allowas-in.
Also, this is the automated way of the same behavior as configuring route-maps
for each peer like:
```
bgp extcommunity-list cpe permit soo 65000:1
!
route-map cpe permit 10
set extcommunity soo 65000:1
...
route-map cpe deny 10
match extcommunity cpe
route-map cpe permit 20
...
```

RFC9234 is a way to establish correct connection roles (Customer/
Provider, Peer or with RS) between bgp speakers. This patch:
- Add a new configuration/terminal option to set the appropriate local
role;
- Add a mechanism for checking used roles, implemented by exchanging
the corresponding capabilities in OPEN messages;
- Add strict mode to force other party to use this feature;
- Add basic support for a new transitive optional bgp attribute - OTC
(Only to Customer);
- Add logic for default setting OTC attribute and filtering routes with
this attribute by the edge speakers, if the appropriate conditions are
met;
- Add two test stands to check role negotiation and route filtering
during role usage.

The `bgp no-rib` command cycles through all the bgp rib tables
and removes them from zebra. Modify the code so that FRR notices
that it is attempting to cycle through the safi's that are two level
tables. In addition these safi's cannot just blindly remove the routes
from the rib as that there are none explicitly.
This code just prevents the crash in bgpd. It does not properly cycle
through and remove the zebra changes made that are explicit to these afi's.
This should be handled as appropriate by the developers on these safi's when
it becomes important to them.

Problem Statement:
=================
PIM Logs are coming at interval of 1 minute although pim
is not enabled.
Root Cause Analysis:
====================
By default, RCPM configures the PIM debugs when router comes up
via script. The product cannot disable PIM even though it is not required.
Hence moving these logs under a new debug option which will not be
enabled by default.
Fix:
====
Added a new option "detail" in the cli:
debug pim nht detail
