Problem

Based on #2075, the logic to detect messages that were missed from the Filter protocol were being detected inside of the Filter SDK implementation. This leads to a tight couple of primary objective of FilterSDK, and reliability goals.

This obstacle also extends to adding further actions that might be taken with additional protocols such as Store pings, and LightPush retries for certain messages.

Solution

Decouple reliability logic into a new ReliabilityMonitor class.

Notes

Contribution checklist:

  • covered by unit tests;
  • covered by e2e test;
  • add ! in title if breaks public API;

based on the original design - we'd need to use it in lightPush too
or do you have another idea how to make retry there happen?

correct. i want to split the PR such that there is cleaner diff and this PR can be followed up with lightpush changes similar to filter (this PR)
