John Spray 7329413705 storage controller: enable setting PlacementPolicy in tenant creation (#7037)
## Problem

Tenants created via the storage controller have a `PlacementPolicy` that
defines their HA/secondary/detach intent. For backward compat we can
just set it to Single, for onboarding tenants using /location_conf it is
automatically set to Double(1) if there are at least two pageservers,
but for freshly created tenants we didn't have a way to specify it.

This unblocks writing tests that create HA tenants on the storage
controller and do failure injection testing.

## Summary of changes

- Add optional fields to TenantCreateRequest for specifying
PlacementPolicy. This request structure is used both on pageserver API
and storage controller API, but this method is only meaningful for the
storage controller (same as existing `shard_parameters` attribute).
- Use the value from the creation request in tenant creation, if
provided.
