IMPALA-10364: Set the real location for external Iceberg tables stored in HadoopCatalog

Impala tries to come up with the table location of external Iceberg
tables stored in HadoopCatalog. The current method is not correct for
tables that are nested under multiple namespaces.

With this patch Imapala loads the Iceberg table and retrieves the
location from it.

Testing:
 * added e2e test in iceberg-create.test

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase, Apache Kudu, Amazon S3, Azure Data Lake Storage, Apache Hadoop Ozone and more!
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate lightning-fast code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including Apache Parquet and Apache ORC.
  • Support for industry-standard security protocols, including Kerberos, LDAP and TLS.
  • Apache-licensed, 100% open source.
