output/ipv6: Add configuration option for shortened IPv6 IP addresses

[jlucovsky]

Continuation of #14420

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

Describe changes:

• Add a configuration variable for choosing shortened IPv6 IP addresses
• Add Rust logic to create a shortened IPv6 address
• Document changes and usage.

Updates:

• Address Clippy issues
• Renamed Rust function to conform with API-naming standard
• Eliminated extra copy in Rust function
• s-v test updates.
• Removed commented-out line from Rust module; added copyright
• Misc doc updates.

Provide values to any of the below to override the defaults.

  link to the pull request in the respective _BRANCH variable.
• Leave unused overrides blank or remove.

This looks good to me (only the line of code before the copyright note a bit unusual :P )!

(But SV PR seems to be missing the min-version)
