Extend anp egress peer

[shireenf-ibm]

base PR: #380
issue: #442

• support Networks field in AdminNetworkPolicyEgressPeer
• add logger to k8s objects and raise some warnings (on IPv6 cidr / nodes field / named ports without match ..)
• more tests (good paths w/wo warnings)
• unit tests on logger warnings
• some "tbd" in the committed code

warning formats: be consistent with current format, for example:

$ ./bin/k8snetpolicy list --dirpath tests/bad_netpols/subdir5/
2024/12/01 15:12:11 Network policy "default/shippingservice-netpol": port name:  "abc" has no match in the configuration of the destination peer "default/shippingservice-1"; it will be ignored, and will not appear in the connectivity results.
0.0.0.0-255.255.255.255 => default/adservice[Deployment] : All Connections
0.0.0.0-255.255.255.255 => default/cartservice[Deployment] : All Connections
0.0.0.0-255.255.255.255 => default/checkoutservice[Deployment] : All Connections

and example from current implementation:

r$ ./bin/k8snetpolicy list --dirpath tests/anp_and_banp_using_networks_with_ipv6_test/
2024/12/01 15:14:13 admin network policy "network-as-egress-peer": Warning  in rule "allow-all-egress-to-intranet": IPv6 addresses are not supported; it will be ignored, and will not appear in the connectivity results.

can be changed to:

admin network policy "network-as-egress-peer": in rule "allow-all-egress-to-intranet": IPv6 addresses are not supported

also, better explain the impact of the "IPV6 not supported" warning in the README documentation.

Please also shorten the warning as I wrote above.
