Commit ac341c01cc446e3e90a17963d47ef20bff8d4b43 in impala's branch refs/heads/master from stiga-huang

IMPALA-11801: Use thrift 0.11.0 in FE when compiling with Apache Hive3
HMS client of Apache Hive3 can't run on thrift versions >= 0.14. Impala
fails to start when compiling with Apache Hive3. This patch switches
back to the old thrift version (0.11.0) used in FE when compiling on
Apache Hive3.
Tests:
- Compiled and launched Impala cluster on Apache Hive3.
- Verified some simple queries.
- Enabling all the tests will be continued in IMPALA-10871.

> Impala 3.x supports both Hive 2 and 3 by a MetastoreShim that is chose at compilation time:
> {code:bash}
> fe/src/compat-hive-2
> └── java/org/apache
> ├── hadoop/hive/common/ValidWriteIdList.java
> └── impala/compat/MetastoreShim.java
> fe/src/compat-hive-3
> └── java/org/apache/impala/compat
> ├── HiveMetadataFormatUtils.java
> └── MetastoreShim.java {code}
> In pom.xml:
> {code:xml}
> <plugin>
> <groupId>org.codehaus.mojo</groupId>
> <artifactId>build-helper-maven-plugin</artifactId>
> <version>1.5</version>
> <executions>
> <!-- Tell maven about our generated files -->
> <execution>
> <id>add-source</id>
> <phase>generate-sources</phase>
> <goals>
> <goal>add-source</goal>
> </goals>
> <configuration>
> <sources>
> ...
> <source>${project.basedir}/src/compat-hive-${hive.major.version}/java</source>
> </sources>
> </configuration>
> </execution>
> </executions>
> </plugin>
> {code}
> Now MetastoreShim evolves to only support CDP Hive which contains some breaking changes of Hive 4.x.
> To support Apache Hive 3.x, we need another MetastoreShim. Some codes that directly use Hive 4 APIs may need to be ignored in compilation, e.g. fe/src/main/java/org/apache/impala/catalog/metastore/*.java
