1. Use generated models in lance-namespace for request response models
to avoid multiple layers of conversions
2. Make sure the API is consistent with the namespace spec
3. Deprecate the table_names API in favor of the list_tables API in
namespace that allows full pagination support without the need to have
sorted table names
4. Add describe_namespace API which was a miss in the original
implementation
Based on https://github.com/lancedb/lance/pull/4984
1. Bump to 1.0.0-beta.2
2. Use DirectoryNamespace in lance to perform all testing in python and
rust for much better coverage
3. Refactor `ListingDatabase` to be able to accept location and
namespace. This is because we have to leverage listing database (local
lancedb connection) for using namespace, namespace only resolves the
location and storage options but we don't want to bind all the way to
rust since user will plug-in namespace from python side. And thus
`ListingDatabase` needs to be able to accept location and namespace that
are created from namespace connection.
4. For credentials vending, we also pass storage options provider all
the way to rust layer, and the rust layer calls back to the python
function to fetch next storage option. This is exactly the same thing we
did in pylance.
## Summary
This PR introduces a `HeaderProvider` which is called for all remote
HTTP calls to get the latest headers to inject. This is useful for
features like adding the latest auth tokens where the header provider
can auto-refresh tokens internally and each request always set the
refreshed token.

This shrinks the size of a local embedded build that can disable all the
default features. When combined with
https://github.com/lancedb/lance/pull/4362 and the dependencies are
updated to point to the fix, this resolves#2567 fully.
Verified by patching the workspace to redirect to my clone of lance with
the PR applied.
```
cargo tree -p lancedb -e no-build -e no-dev --no-default-features -i aws-config | less
```
The reason that lance itself needs to change too is that many
dependencies within that project depend on lance-io/default and lancedb
depends on them which transitively ends up enabling the cloud
regardless. The PR in lance removes the dependency on lance-io/default
from all sibling crates.
