v3.28.0

Important notice

(#4048) PR adds a toggle to change the behaviour of PBS HTTP client DNS resolution to a round-robin. Presently, HTTP client DNS resolver always takes the first IP address from the DNS response, even if there are multiple addresses. This creates a heavy load skew towards the first IP in the list and makes one of the HTTP load balancing techniques ineffective.

For now, old behaviour is kept intact for the sake of having a grace period, but this will change in one of the feature releases. New behaviour is to take and use all IP addresses from the DNS response in a round-robin manner, which should lower the load on the adapter endpoint in some cases.

Host companies will still be able to opt in old DNS resolution behavior if they desire so.
