Better descriptions for dials that failed due to being for private addresses #96
Description
I sometimes see failures reported like:
Libp2p connected: failed to dial: failed to dial 12D3KooWBiV3fTZuzSDDgzwcgqBjRTmnbxaDjnKtzcV3K3v9CMHt: no good addresses

For most users seeing gater disallows connection to peer is probably not particularly helpful. Perhaps it'd be better not to report on these failed private addresses or to pre-filter them and perhaps add an error like 10 private addresses found.
