HADOOP-10579. Add match expressions to find command

[LamiumAmplexicaule]

Description of PR

Add match expressions to find command.
This pull request is based on the patch attached to the ticket in HADOOP-10579 and HADOOP-10580.

The main changes from the original patch are as follows:

• Add support for JUnit 5
• Add additional test cases
• Add a (all) to the symbolic notation target in Perm.java
• Remove -regextype
• Use Pattern flags for case-insentive regex matching
• Minor fixes
  • Replace equals("") with isEmpty()
  • Replace throw new IOException with throw new IllegalArgumentException
  • Other small cleanup changes.
• Code reformatting

How was this patch tested?

• Pass the tests in hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/fs/shell/find on local.

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

Thank you @LamiumAmplexicaule for your work. Several comments:

• Would you add a test case to make sure multiple options are handled correctly? For example: -mtime 10 -regex *.parquet
• Would you document the new expressions in FileSystemShell.md?
• Would you fix the checkstyle issues and trailing whitespaces warned by the CI?

[aajisaka]

Here are the review comments for the tests:

[LamiumAmplexicaule]

Thank you @aajisaka for your review.

• Would you add a test case to make sure multiple options are handled correctly? For example: -mtime 10 -regex *.parquet

I think it’s Find.java and And.java that ensures multiple expressions work correctly, and TestFind.java and TestAnd.java that tests this behavior.
Since processOptionsNoop, processOptionsA and processOptionsAnd already exist in TestFind.java, and we already have TestAnd.java, I believe their existing tests provide sufficient coverage.
Do you think any additional tests are necessary?

• Would you document the new expressions in FileSystemShell.md?

I documented it in this commit a046ee5.

• Would you fix the checkstyle issues and trailing whitespaces warned by the CI?

I fixed it in the following commit.

• a424a11
• 81fb503

Thank you for the detail. Now I think additional tests are unnecessary.

The CI runs mvn install on the trunk, so if we change any of the org.apache.hadoop.fs.shell.* or modify testHDFSConf.xml, the test org.apache.hadoop.cli.TestHDFSCLI should fail.
