I don't think resolving a single address should necessarily fail all addresses, but gracefully degrading the whole request is a fair place to start.

There is only one possible ways how this can fail, because there is only one case Addr() returns an error, and this is because there are no servers available.
Therefore subsequent calls of Addr() are very likely to fail as well.
Instead of returning the error, `FilterChunks` returns the full, unfiltered list of chunks. This makes sure that queries do not fail if no bloom gateway instances are available. Signed-off-by: Christian Haudum <[email protected]>
