feat: allow disabling value and provider storage/messages #400

That's a little funky.
One question wrt correctness is that the local option affects the propagation of messages to the network.
Ie if we disable values/providers, then GetValue and FindProviders will short-circuit and not send any messages to the network.
However, we might have peers that are able to answer these queries because they have these options enabled.
Is this intended?

is this correct behaviour? We might know a peer that supports GetValue and so on.

Yes. This feature is intended to be used in private/forked DHTs with custom protocol names (e.g., the Filecoin DHT). |
@Stebalien Could this get documented in the code? Maybe on the struct values: |

@lanzafame I'm documenting the options. |

None. It was only ever used for validating IPNS records and:
