Remove secio usage as default connection encryption

[vasco-santos]

We should remove secio as the default connection encryption module in libp2p daemon. Making noise used by default and remove the option to use secio/noise at all.

Currently, we are running interop tests for libp2p using secio unless explicitly setting noise, which is not desirable.

We should do this together with go-libp2p-daemon, otherwise we will need to explicitly set noise as the used module in the interop tests when spawning go nodes.
