feat: integrate reputation manager into Lightpush behind a feature flag

[s-tikhomirov]

Description

This PR integrates a reputation system designed as part of the incentivization PoC into the Lightpush protocol behind a feature flag (reputation).

A Lightpush client uses the reputation manager to keep track of peers it used previously to publish messages. Peers that had failed at publishing a message get assigned a negative reputation and will not be chosen for future requests. If, however, a neutral- or positive-reputation peer isn't selected by the peer manager after a maximum number of attempts (10), a negative-reputation peer is still used.

This is a countinuaton of #3166, #3264, and #3293 with associated deliverable waku-org/pm#245.

Changes

• add an optional reputation manager for Lightpush client behind a feature flag
• add tests for the reputation manager
• refactor the publishToAny logic for lightpush
• add reputation-based logic to peer selection in a Lightpush client
