Java 17 and GitHub Workflow Updates

Development Team,

Thanks to reviews from Mike Thomsen and Paul Grey, support for building the
NiFi project on Java 17 is now in the main branch.

The GitHub continuous integration workflow now includes a fourth
environment:

Ubuntu Zulu JDK 17 EN

Although some dependencies may cause runtime issues with Java 17, this new
build target will help highlight and correct particular issues. For the
purpose of compatibility, restricted reflective access is one of the most
important differences in Java 17.  Java 11 flags these issues as illegal
reflective access warnings, but Java 17 prevents these operations.

New issues with particular components should be flagged and addressed using
the standard Jira tracking process.

This is also a good time to mention ongoing work related to JUnit 5. Big
thanks to Mike Thomsen for working through numerous modules and multiple
rounds of feedback to update a majority of components to JUnit 5! All new
test code should use JUnit 5 org.junit.jupiter components.  Some work still
remains to convert various modules, which can be tracked through sub-tasks
under the following Jira issue:

https://issues.apache.org/jira/browse/NIFI-9084

Finally, shout out to Paul Grey for his efforts to improve the reliability
of the NiFi system tests on GitHub.  The resource-constrained GitHub
runners can expose test stability problems that are difficult to track
down, but thanks to Paul's work, the stability of the system tests on
GitHub has improved.

Regards,
David Handermann

For sure many thanks.  Getting stable builds and keeping them there is
key.  And supporting the newer JVMs in a timely manner is as well.

Thanks!
