* The metrics-label-values for prepared statements are kept as
they already represent a fixed set
- Use of observer observable pattern to inform delivery_monitor about subscription state
- send_monitor becomes a publish observer of lightpush and relay
- deliver monitor add more protection against possible crash and better logs
- creating a separate proc in store client for delivery monitor
* bump_dependencies.md: add nim-results dependency
* change imports stew/results to results
* switching to Nim 2.0.8
* waku.nimble: reflect the requirement nim 1.6.0 to 2.0.8
Adding --mm:refc as nim 2.0 enables a new garbage collector that we're
not yet ready to support
* adapt waku code to Nim 2.0
* gcsafe adaptations because Nim 2.0 is more strict
