Peer alias list

[soulexporter]

Public keys become very confusing. We often interact with the same nodes/node managers.

When we could decide optionally to prepare a list of our most used peers (pubkeys) linked to an Alias (nobody has to understand that alias, just the person using it for own reference) it could help with

1. building routes (make optional to use pubkey or alias) in configureHops.sh
2. seeing where a problem occurs when the roundTrip.sh runs into an issue
