Before libp2p 0.50.0 we used a quorum of one to fetch records from the DHT. In the pr that upgraded
to libp2p 0.50.0 we accidentally changed this behavior. This pr brings back the old behavior of
using a qorum of one and thus, a faster discovery. After finding the first value, we directly finish
the query. There was also another behavior change in libp2p, they stopped automatic caching on
remote nodes. This pr also brings back the remote caching on nodes that are nearest to the key from
our point of view of the network.
The pr that changed the behavior in libp2p: https://github.com/libp2p/rust-libp2p/pull/2712
