Test ingest_benchmark with different stripe size and also PostgreSQL version 17

[Bodobolero]

We want to verify if pageserver stripe size has an impact on ingest performance.
We want to verify if ingest performance has improved or regressed with postgres version 17.

Summary of changes

• Allow to create new project with different postgres versions
• allow to pre-shard new project with different stripe sizes instead of relying on storage manager to shard_split the project once a threshold is exceeded

Replaces #10509

Test run https://github.com/neondatabase/neon/actions/runs/12986410381

We have two other changes deployed to staging that we need to do performance testing for (L0 backpressure and parallel reads). Changing the stripe size too would make it hard to measure the impact of each change in isolation. Should we hold off on this until we've stabilized staging a bit?

[erikgrinaker]

Change LGTM.

@erikgrinaker
The change still tests the new_project as before.
It just adds additional variants in the strategy.
We also will continue to report the non-presharded, default stripe size new_project in the weekly perf report
