NIFI-11673 Remove Legacy TLS Configuration Versions

[exceptionfactory]

Summary

NIFI-11673 Removes legacy TLS protocol versions from the TlsConfiguration interface along with methods based on evaluation of Java version information.

Previous logic defaulted to TLSv1.2 for Java 8 and TLSv1.3 for Java 11 when calling several helper methods on TlsConfiguration. The TlsPlatform utility class provides feature-based detection and has been used in a number of framework and extension components. With the removal of Java 8 support from the main branch, the Java version number checking is no longer necessary.

Additional changes include applying the SSL Protocol property to the HTTP Notification Service for NiFi Bootstrap and removing test methods no longer necessary with the standardization of available TLS protocol versions.

For cluster socket communication, the TlsPlatform methods replace the Java version-based methods from TlsConfiguration while providing equivalent functionality.

Thanks for the change @exceptionfactory! Tested on a secured cluster, LGTM. Merging to main.

Noticed test failures in the nifi-toolkit-tls module in my last build after rebase. It could be a local env issue, but for further investigation, I'm revoking my approval for safety's sake.

It was an env issue. Merging to main.
