prabhataravind 26ade35fdf [image_config]: Update DHCP rate-limit (#17132)
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.

Microsoft ADO 25776614:

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