#### Description of PR
NIFI-8462 Refactors the `PutSyslog` and `ListenSyslog` Processors to use
Netty for socket communication. This approach replaces the use of custom
socket channel dispatcher classes in `nifi-processor-utils`. Leveraging the
Netty `SslHandler` also removes the use of custom `SSLSocket` and `SSLEngine`
handling in `nifi-security-socket-ssl` classes. This approach resolves latent
issues with TLS 1.3 communication in these processors, described in NIFI-7468.
The new `nifi-event-transport` module abstracts communication handling for
both UDP and TCP communication, providing interfaces and classes that can be
leveraged in other components. Refactoring other components to leverage Netty
should eventually remove the need for error-prone `SSLEngine` handling in
custom classes.
Changes also include refactored unit tests for `PutSyslog` and
`ListenSyslog`, eliminating the use of mocked senders and removing unnecessary
integration tests.
