[SPARK-22128][CORE][BUILD] Add paranamer dependency to core module

## What changes were proposed in this pull request?

With Scala-2.12 profile, Spark application fails while Spark is okay. For example, our documented `SimpleApp` Java example succeeds to compile but it fails at runtime because it doesn't use `paranamer 2.8` and hits [SPARK-22128](https://issues.apache.org/jira/browse/SPARK-22128). This PR aims to declare it explicitly for the Spark applications. Note that this doesn't introduce new dependency to Spark itself.

https://dist.apache.org/repos/dist/dev/spark/3.0.0-SNAPSHOT-2019_01_09_13_59-e853afb-docs/_site/quick-start.html

The following is the dependency tree from the Spark application.

**BEFORE**
```
$ mvn dependency:tree -Dincludes=com.thoughtworks.paranamer
[INFO] --- maven-dependency-plugin:2.8:tree (default-cli)  simple ---
[INFO] my.test:simple:jar:1.0-SNAPSHOT
[INFO] \- org.apache.spark:spark-sql_2.12:jar:3.0.0-SNAPSHOT:compile
[INFO]    \- org.apache.spark:spark-core_2.12:jar:3.0.0-SNAPSHOT:compile
[INFO]       \- org.apache.avro:avro:jar:1.8.2:compile
[INFO]          \- com.thoughtworks.paranamer:paranamer:jar:2.7:compile
```

**AFTER**
```
[INFO] --- maven-dependency-plugin:2.8:tree (default-cli)  simple ---
[INFO] my.test:simple:jar:1.0-SNAPSHOT
[INFO] \- org.apache.spark:spark-sql_2.12:jar:3.0.0-SNAPSHOT:compile
[INFO]    \- org.apache.spark:spark-core_2.12:jar:3.0.0-SNAPSHOT:compile
[INFO]       \- com.thoughtworks.paranamer:paranamer:jar:2.8:compile
```

## How was this patch tested?

Pass the Jenkins. And manually test with the sample app is running.

Closes apache#23502 from dongjoon-hyun/SPARK-26583.
