chore: upgrade libp2p package

[mcmxcdev]

Description

• upgrade go-libp2p and its related libs
• update method calls due to go-libp2p version upgrade
• remove duplicate sync import in network.go
• run go mod tidy
• update go version in testing.yml to 1.17
• update docker container to use alpine 3.15

Please note that lp2pdiscovery is updated to use the mdns_legacy module which keeps compatibility with the current code.
There is also mdns which should probably be used instead when refactoring the code.

make docker is probably failing due to https://github.com/lucas-clemente/quic-go only supporting go 1.16 and higher I assume, while the docker image is using go 1.15

make unit_test is passing for me locally, but fails in the CI, any idea why? It might also be related to the newer go version locally than in the CI.

I probably caused these incompatibilities by running go mod tidy?

You can update alpine version inside dockerfile to support go version 17:

FROM alpine:3.15 as builder

RUN apk add --no-cache git go gmp-dev build-base g++ openssl-dev
RUN go version
...

About the mDNS legacy version, they have plan to remove it. Look at here: https://github.com/libp2p/go-libp2p/pull/1192/files
It's better to not use it anymore.

Shouldn't be. Updating go version in workflow should fix it: https://github.com/zarbchain/zarb-go/blob/01ca59d44f778a7fbeb2de02debbddcd91909f91/.github/workflows/testing.yml#L15

go-version: 1.17.x

I tried to update the respective code but don't know how exactly. I would hand this over to you.
