[Core] Reduce port system load by comparing entities and upserting ch…

…anged entities for all types of integrations (#1336)

# Description

What - Introduced a new entity diff resolver to reduce port system load
by comparing entities and upserting changed entities only for all types
of integrations (not only saas)

Why - after a poc , we see that the fix works well and we want to have
it for all the integrations, not only saas

How - removed the if ocean saas check

## Type of change
- [ ] New feature (non-breaking change which adds functionality)


### Core testing checklist

- [ ] Integration able to create all default resources from scratch
- [ ] Resync finishes successfully
- [ ] Resync able to create entities
- [ ] Resync able to update entities
- [ ] Resync able to detect and delete entities
- [ ] Scheduled resync able to abort existing resync and start a new one
- [ ] Tested with at least 2 integrations from scratch
- [ ] Tested with Kafka and Polling event listeners
- [ ] Tested deletion of entities that don't pass the selector
