…lease renewal interval (not yet merged upstream)
…ill be in 3.4.3)

Backport of apache#7886 to hubspot-3.3.6. Replaces all uses of
deprecated-for-removal Subject.getSubject()/Subject.doAs() APIs with
the new SubjectUtil compatibility layer that uses MethodHandle to
dispatch to Subject.current()/Subject.callAs() on Java 18+ and falls
back to the legacy APIs on older JVMs. This unblocks running on Java 25
where the old APIs throw UnsupportedOperationException.

Changes:
- Add SubjectUtil utility class (from upstream) with Java version
  adaptive dispatch via MethodHandle
- Add TestSubjectUtil (ported from JUnit 5 to JUnit 4 for 3.3.6)
- KerberosAuthenticator: Subject.getSubject() -> SubjectUtil.current()
- UserGroupInformation.getCurrentUser(): Subject.getSubject() ->
  SubjectUtil.current()
- UserGroupInformation.doAs(PrivilegedAction): Subject.doAs() ->
  SubjectUtil.doAs()
- UserGroupInformation.doAs(PrivilegedExceptionAction): Subject.doAs()
  -> SubjectUtil.doAs()
