This adds a new step for checking whether an index is allocated correctly based on the rules added prior to running the shrink step. It also fixes a bug where for shrink we are not allowed to have the shards relocating for the shrink step. Resolves elastic#34938

We need to add a check for the shard being started here too otherwise we will end up with the same issue on the allocate action but it will be harder to diagnose

I'd like to address that in a separate PR, since I think it warrants more testing for the full ramifications, would that be okay with you?

ok, could you create an issue so we can track the extra work and it doesn't get missed?

This adds a new step for checking whether an index is allocated correctly based on the rules added prior to running the shrink step. It also fixes a bug where for shrink we are not allowed to have the shards relocating for the shrink step. This also allows us to simplify AllocationRoutedStep and provide better feedback in the step info for why either the allocation or the shrink checks have failed. Resolves #34938

This is a follow-up from elastic#35161 where we now check for started and relocating state in `AllocationRoutedStep`. Resolves elastic#35258
