nmcli: add ipv4.routing-rules, ipv4.may-fail options and disabled to method6

[omula]

Summary

I am trying to configure our network setup which is possible with nmcli command line but there are some missing options in the ansible collections which prevents us from using it. Adding this options will extend the possible configuration that the collection can do and get closer to nmcli command capabilities.

Issue Type

Feature Idea

Component Name

nmcli

Additional Information

This type of configuration is for example used for Lustre and Multi-Rail environments.
