Support scope-down statements in manager rules

[jgournet]

Describe the Feature

Currently, scope_down_statement is only supported in rate_based_statement.
It would be great if it was supported in other rules too (I am particularly interested in adding it into managed_rule_group_statement_rules)

Expected Behavior

Being able to have a scope_down_statement in managed_rule_group_statement_rules

Use Case

Trying to use this module for managed_rule_group_statement_rules - not having scope_down_statement means I would have to write my own rules, which defeats the purpose of using this module.

Describe Ideal Solution

I guess it is "just" a big copy/paste job of "scope_down_statement" from rate_based_statement into managed_rule_group_statement_rules.
