feat(script): add a bootstrap script for setting up Lakekeeper in the local development environment

[mengw15]

What changes were proposed in this PR?

Lakekeeper is a open-sourced, apache-licensed IcebergRESTCatalog implementation. This PR adds the Lakekeeper bootstrap script for developers to setup the Lakekeeper conveniently.

Lakekeeper provides pre-built binaries for macOS ARM64, Linux x86_64, and Linux ARM64
(releases). Windows is not supported by Lakekeeper upstream, so this script targets macOS and Linux developers only.

Any related issues, documentation, discussions?

Issue: close #4353 .
Documents: wiki page.

How was this PR tested?

Manually tested by launching Lakekeeper with this script and set it as the rest catalog for Texera.

Thanks for putting this together! Few suggestions:

1. Remove parse-storage-config.py

The Python script + pyhocon dependency adds significant friction (not everyone has pyhocon installed, and it's a niche package). This can be eliminated entirely because storage.conf already supports env var overrides via ${?STORAGE_*} syntax. The bootstrap script can read the same env vars with the same defaults:

LAKEKEEPER_BASE_URI="${STORAGE_ICEBERG_CATALOG_REST_URI:-http://localhost:8181/catalog}"
WAREHOUSE_NAME="${STORAGE_ICEBERG_CATALOG_REST_WAREHOUSE_NAME:-texera}"
S3_REGION="${STORAGE_ICEBERG_CATALOG_REST_REGION:-us-west-2}"
S3_BUCKET="${STORAGE_ICEBERG_CATALOG_REST_S3_BUCKET:-texera-iceberg}"
S3_ENDPOINT="${STORAGE_S3_ENDPOINT:-http://localhost:9000}"
S3_USERNAME="${STORAGE_S3_AUTH_USERNAME:-texera_minio}"
S3_PASSWORD="${STORAGE_S3_AUTH_PASSWORD:-password}"

2. Remove awscli dependency for MinIO bucket operations

Requiring awscli just to create a bucket is heavy. Please use curl with S3 API directly (a simple PUT to http://endpoint/bucket-name)

3. Hardcoded binary path requires editing the script

LAKEKEEPER_BINARY_PATH="" at line 37 forces users to edit the script source. Consider:

• Accept it as a CLI argument or env var
• Default to lakekeeper (assuming it's on $PATH)
• Mention brew install lakekeeper in the setup instructions (works on macOS)

4. Cross-platform considerations

Lakekeeper provides pre-built binaries for macOS ARM, Linux x86_64, and Linux ARM. Seems windows doesn't support it. Please mention it in the PR description
