Add configuration option to set implicit default filter-addrs and filter-protocols from IPIP-484

[lidel]

While someguy supports IPIP-484 in queries, there is no filtering by default.

It would be useful to have opt-in filtering that limits the default output, eg. to skip GraphSync results proxied from IPNI at cid.contact in deployments that will never benefit from it because clients only support Bitswap or HTTP.

Implementation proposal

• defaults remain the same, no filtering by default
• keep it simple
  • new config options named same as ones from IPIP-484 (--filter-addrs and ---filter-protocols)
  • when set, apply them to the boxo/routing/http/client instance someguy uses.
