TAJO-1577: Add test cases to verify join plans

[jihoonson]

This patch is based on @navis's first work (#558).
Here are the summary of changes.

• Most join query tests are executed with the SimpleTest annotation. It includes tests of logical plan, global plan, and query execution result.
• Join tests are categorized into 6 groups, i.e., TestInnerJoinQuery, TestInnerJoinWithSubQuery, TestOuterJoinQuery, TestOuterJoinWithSubQuery, TestMultipleJoinTypes, and TestJoinOnPartitionedTables.
  • I've newly added the NamedTest annotation to reuse files for datasets and queries.
  • Some temporal tables are shared across different join tests.
  • Every join test is executed with hash join, sort-merge join, hash-broadcast join, and sort-merge-broadcast join.

Great job! The patch looks good to me. The change looks straightforward. You may spend lots of time on changing many tests.

Here is my +1.
