p2p: support dns entrypoints #3156

Libp2p accepts DNS entrypoint for the node. Example:

/dns4/bootstrap-0.mainnet.filops.net/tcp/1347/p2p/12D3KooWCVe8MmsEMes2FzgTpt9fXtmCY7wrq91GRiaC8PHSCCBj

In the existing deployment scheme we create several nodes and then connect every other node to them. It makes deployment more complex, and more importantly, relies on IP addresses being the same all the time.

Instead, in the new deployment scheme, we will generate entrypoints in advance and share them for every node in the cluster.
