implement SNS Filter/operators $or, suffix, equals-ignore-case

[bentsku]

Motivation

As reported in #9738, AWS launched new operators for SNS filtering. suffix and equals-ignore-case are pretty simple to implement, but $or necessitated a quite consequent rewrite, as the logic can get quite convoluted pretty fast. It quickly creates a lot of different forks, where one rule can have multiple branches and a payload can have multiple branches too if it contains array.

Changes

• switched the model for the policy, making it a list where each item of the list is an OR condition. This comes from the documentation of AWS: https://docs.aws.amazon.com/sns/latest/dg/and-or-logic.html

TODO

What's left to do:

• write some AWS validated tests to check the limits, and verify some complicated cases
• write better doc strings, as the logic changed a bit, and rename some obscure variable names
