This commit reverts the previous metrics behavior. Namely:
- adhering to --metrics-path flag
- listening on 0.0.0.0:8888 instead of 127.0.0.1:8080
Note that 8888 is the default IPFS debug (aka. metrics) port.
See https://github.com/mxinden/rust-libp2p-server/blob/master/src/metric_server.rs for previous behavior.
Pull-Request: #4392.
One needs to specify a version of `libp2p` dependeny in `misc/server/Cargo.toml` or import as a workspace dependency, in order to publish to crates.io.
This commit does the latter for the sake of consistency with the other libp2p-* dependencies.
Pull-Request: #4391.
