John Spray 71d004289c storcon: in shard splits, inherit parent's AZ (#9946) ...

## Problem

Sharded tenants should be run in a single AZ for best performance, so
that computes have AZ-local latency to all the shards.

Part of https://github.com/neondatabase/neon/issues/8264

## Summary of changes

- When we split a tenant, instead of updating each shard's preferred AZ
to wherever it is scheduled, propagate the preferred AZ from the parent.
- Drop the check in `test_shard_preferred_azs` that asserts shards end
up in their preferred AZ: this will not be true again until the
optimize_attachment logic is updated to make this so. The existing check
wasn't testing anything about scheduling, it was just asserting that we
set preferred AZ in a way that matches the way things happen to be
scheduled at time of split.
