• Fix replica URL parsing for IPv6 URLs for icmp and tcp protocols. Previously, an IPv6 URL formatted as eg. tcp://[::1]:80 would be passed as eg. tuple ('[::1]', 80) to the probe, which is not resolvable and would incur a failure. The correct tuple format is now being passed, which is eg. ('::1', 80).
• Implement a stricter replica URL parsing from configuration in ReplicaURL, for icmp and tcp protocols. Extraneous non-used URL port and segments (where applicable) are now considered as invalid.
