Support labels projection for Parquet Queryable

[yeya24]

Is your feature request related to a problem? Please describe.
parquet-common library recently adds support for labels projection prometheus-community/parquet-common#118. This allows fetching only required columns when materializing and should greatly reduce data downloaded.

Describe the solution you'd like
To enable this feature, there are several steps required:

• Add thanos engine optimizer to enable projection pushdown optimization Add projection pushdown optimizer thanos-io/promql-engine#549
• Upgrade parquet-common and expose config to honor projection hints in Parquet queryable
• Since projection is not supported by Ingester, we may need to handle it properly in querier to only do projection pushdown when ingester is not queried.
