output/ipv6: Add configuration option to shorten IPv6 IP addresses

[jlucovsky]

Continuation of #14636

Add a configuration option for outputting shortened IPv6 addresses per RFC-5952

The configuration option:
logging.ipv6-addr-shorten has a default value of no.

When set to yes, IPv6 addresses will be shortened everywhere they are output. E.g., the IPv6 address fe80:0000:0000:0000:020c:29ff:faf2:ab42 will be output as fe80::20c:29ff:faf2:ab42
