Preston Van Loon 1dab5a9f8a Feature: --p2p-colocation-whitelist flag to allow certain IPs to bypass colocation restrictions (#15685)
* Add flag for colocation whitelisting. --p2p-ip-colocation-whitelist

This change updates the peer IP colocation checking to respect the
configured CIDR whitelist (--p2p-ip-colocation-whitelist flag).

Changes:
- Added IPColocationWhitelist field to peers.StatusConfig
- Added ipColocationWhitelist field to Status struct to store parsed IPNets
- Parse CIDR strings into net.IPNet in NewStatus constructor
- Updated isfromBadIP method to skip colocation limits for whitelisted IPs
- Pass IPColocationWhitelist from Service config when creating Status

The IP colocation whitelist allows operators to exempt specific IP ranges
from the colocation limit, useful for deployments with known trusted
address ranges or legitimate node clustering.

Only check if an IP is in the whitelist when the colocation limit
is actually exceeded, rather than checking for every IP. This is
more efficient and matches the intended behavior.
