* Configure protocolVersion for Identify protocol
Allows the protocolVersion field of the Idenfity protocol to be
configured on the host. The current value is fixed for what appears to
be for backwards compatibility with IPFS which makes it difficult for
non-IPFS protocols to use the library.

Fix an issue where the protocolVersion string for the Identify protocol
was wrongly being assigned the agentVersion string.

The new `Filters` option allows users to take ownership of the `Filters` struct, and is suitable for cases where the addresses you want to accept/deny change dynamically.
Instead of using a global variable.
This also:
* Adds an option to the identify service to set the user agent.
* Removes the ability to pass an identify service to NewHost as any reasonable
Identify service already needs to be constructed with an instance of the host.
So, in go-ipfs at least, we *don't* pass the listen addresses into the libp2p
constructor. Instead, we specify them later.
This option allows us to tell libp2p to not listen by default.
