Deduplicate incoming relays from configuration

[ralexstokes]

Both the builder and the boost components take a list of relays as part of the configuration.

You could currently provide duplicates and this would not really be useful in any way.

It would be nice to filter out duplicate relays when parsing from the configuration.

This could also be an opportunity to build out a "relay set" abstraction, as some of the logic is getting duplicated across builder and boost.
