As a developer I can filter/blacklist peers

[frrist]

Description

In go-filecoin when a node fails the hello protocol (because they have a different genesis block or wrong version) we disconnect from them. However, we will frequently reconnect to them immediately. This is undesirable as we would prefer to not reconnect to this peer again for some time.
A solution we initially considered was the Backoff method in go-libp2p-swarm, but we were informed this component is for internal use only.

Acceptance criteria

• As a developer I can configure my application to:
  • avoid reconnecting to a peer for some configurable amount of time. (e.g. in go-filecoin a peer may keep the same peerID but update its version, we would not want to blacklist a peer in this scenario).
  • Completely blacklist a peer from reconnecting.
