Use user's relay list

[jb55]

We should fetch a users relay list if we don't have it. We can use our current hardcoded list as our bootstrap list.

Some open questions:

• What relay list should we use when we have multiple users?
• We could use a union of the lists for the alpha release
• Future releases may add them all as active connections, and simply subscribe to the correct ones based on context?

On startup, we use the bootstrap relay list to try and fetch the users k:10002 record.

Do we block other progress while we wait? Or should we proceed w/ setting up the timelines w/ the bootstrap list while we wait?

[ksedgwic]

Another question: do we union in the k:3 relays with the k:1002? Are there other sources of relays I should be considering?

@ksedgwic has a proposal for a method

@jb55 to review soon :tm:

@ksedgwic advises just thumbs up is sufficient; complete review not needed. Hardening work remainaing, plenty to do with thumbs up.

@ksedgwic added:

-bootstrapping (if nothign else is working) -local relays will always be used. set added with advertised relays (solely from network) -forced relays - if see in command; doesnt update

@ksedgwic maybe there is a need for "fixed relays" down the road

[alltheseas]

@jb55 - overlapping relays sets - might make sense to have transiently maintained relays list. maintain relays, but dont reconenct all the time.

Multiple profiles may require use of different relays.

@ksedgwic - when adding subscription over available relays - "this subscription does not go over this relay".

Subscriptions need an additional argument - "what kind of subsription is this - read, write etc."

Easy to add
