### Why I did it
The json.hpp header file from that package is used in the sonic-swss-common build. An old version of that header file (from 2016) has been checked into the sonic-swss-common repo. However, since then, there have been changes to that header file, and starting with GCC 12 in Bookworm, generates some errors about variables being possibly uninitialized before use.
##### Work item tracking
- Microsoft ADO **(number only)**: 25027439
#### How I did it
To fix this, install the nlohmann-json3-dev package, and allow using the header file from the Debian package instead of a static checked-in version. The version in Debian Bullseye is much newer than this version.
#### How to verify it
With this change alone, sonic-swss-common will still be using the json.hpp file in its own codebase. The change to actually use the system header file instead of the local header file will happen in a separate PR in the necessary repoes.

Change DHCP rate limit in SONiC copp configuration to 100 PPS as this is
necessary to ensure that DHCP flood does not cause LACP/BGP flaps in all
scenarios
This is an extension to the change in image_config: copp: Enable rate limiting
for bgp, lacp, dhcp, lldp, macsec and udld #14859 and sonic-mgmt change in
[tests/copp]: Update copp mgmt tests to support new rate-limits sonic-mgmt#8199
Why I did it
300 PPS is not sufficient to prevent LACP/BGP flaps in all cases. 100 PPS seems to
provide better resiliency against DHCP traffic flood to CPU.

Send DHCP broadcast packets to DUT and verify that they are trapped to CPU at 100 PPS.

* [chassis/multi-asic] Make sure iBGP session established as directly connected (#16777)
What I did:
Make Sure for internal iBGP we are one-hop away (directly connected) by using Generic TTL security mechanism.
Why I did:
Without this change it's possible on packet chassis i-BGP can be established even if there no direct connection. Below is the example
- Let's say we have 3 LC's LC1/LC2/LC3 each having i-BGP session session with each other over Loopback4096
- Each LC's have static route towards other LC's Loopback4096 to establish i-BGP session
- LC1 learn default route 0.0.0.0/0 from it's e-BGP peers and send it over to LC2 and LC3 over i-BGP
- Now for some reason on LC2 static route towards LC3 is removed/not-present/some-issue we expect i-BGP session should go down between LC2 and LC3
- However i-BGP between LC2 and LC3 does not go down because of feature ip nht-resolve-via-default where LC2 will use default route to reach Loopback4096 of LC3. As it's using default route BGP packets from LC2 towards LC3 will first route to LC1 and then go to LC3 from there.
Above scenario can result in packet mis-forwarding on data plane
How I fixed it:-
To make sure BGP packets between i-BGP peers are not going with extra routing hop enable using GTSM feature
neighbor PEER ttl-security hops NUMBER
This command enforces Generalized TTL Security Mechanism (GTSM), as specified in RFC 5082. With this command, only neighbors that are the specified number of hops away will be allowed to become neighbors. This command is mutually exclusive with ebgp-multihop.
We set hop count as 1 which makes FRR to reject BGP connection if we receive BGP packets if it's TTL < 255. Also setting this attribute make sure i-BGP frames are originated with IP TTL of 255.
How I verify:
Manual Verification of above scenario. See blow BGP packets receive with IP TTL 254 (additional routing hop) we are seeing FIN TCP flags as BGP is rejecting the connection
