Rust Hydration

[bitner]

• update pydantic requirement to ~=2.0
• update docker and ci workflows to build binary wheels for rust additions to pypgstac
• split docker into database service and python/rust container
• Modify scripts to auto-generate unreleased migration
• Add pre commit tasks to generate migration and to rebuild and compile pypgstac with maturin for rust
• Add private jsonb column to items and collections table to hold private metadata that should not be returned as part of a stac item
• Add generated columns to collections with the bounding box as a geometry and the datetime and end_datetime from the extents (this is to help with forthcoming work on collections search)
• Add PLRust to the Docker postgres image for forthcoming work to add optional PLRust functions for expensive json manipulation (including hydration)

I'm not very familiar with the postgres internals of pgstac, but the Rust code and Rust CI changes look good

@bitner, This PR is blocking some other PR and projects. What do you think about splitting this into multiple PR (e.g #197) so we can move forward.

Main blocker is me being out of the office. I'm hoping to get everything merged on Monday. If i hit any road blocks I'll split things up

@kylebarron @gadomski I updated to use pyo3 rather than serde using sample code from @gadomski. As we discussed last week, my main goal here is to get the infrastructure into place for incorporating rust with hopefully a bit of a win on hydration performance, but more with an eye towards moving much of the json parsing as well as things like injecting links into rust in the future.

@bitner I made a couple of touchups to the Rust code and the pypgstac Dockerfile. LGTM for a first-pass, .

Thanks @gadomski and @kylebarron for all the review / code! I'm going to merge this now, but not going to cut a release until I do some heavy benchmarking with PC.
