https://issues.apache.org/jira/browse/SOLR-16995

Description

I am resuming refactoring started earlier (#1928, #1981, #2039) with the goal of simplifying/centralising code related to replica types. The end goal would be to avoid having if (replicaType == Replica.Type.*) scattered across the codebase, and to make it easier to add new replica types.

Solution

This PR adds new attributes to replica types that specify how they behave when they are followers, i.e., the leader replica forwards updates to them.

Tests

Existing tests should pass, no change of behaviour.
