Simplify how connection set is printed

[zivnevo]

example:

protocol: TCP src-ports: 1-442,444-65535 dst-ports: 443; protocol: TCP src-ports: 443

should be simplified to

protocol: TCP dst-ports: 443; protocol: TCP src-ports: 443

explore other examples to generalize the problem

[ShiriMoran]

should also address
np-guard/vpc-network-config-analyzer#826 (comment)

[ShiriMoran]

should also refactor the function w.r.t. the "protocol" header so that it is consistent and always printed
