feat: integrate iceberg initial load support via jvm grpc

[iamKunalGupta]

• add quarkus with grpc for jvm
• expose required routes for appends, changes and setup tables

Currently Gradle is used for build and dev and additionally does the following (via Quarkus Tasks):

• Generates the corresponding java files for proto
• Generates the GrpcService Interfaces for extending and injecting

TODOS:

• [ ] Iceberg partitioning support
• [x] UI Changes
• [ ] ~Table namespace support~ planned for later
• [x] More support
  • [x] Catalogs
    • [x] JDBC
    • [x] Hive
  • [x] FileIO
    • [x] S3
    • [x] GCS - supported via S3 + HMAC based access
