[NETCONF-1030] transport-tcp transport does not work with plain NioSocketChannel

Relates — Thu, 3 Aug 2023 16:32:43 +0000

STR:

disable epoll test dependency in transport-tcp module (also works for transport-tls and transport-ssh) then execute unit tests within same module

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-transport-native-epoll</artifactId>
    <classifier>linux-x86_64</classifier>
    <scope>test</scope>
</dependency>

Actual result:

NettyTransportSupport utility artifact fails initialization with exception

Caused by: java.lang.IllegalStateException: channel not registered to an event loop

Expected:
Both Epoll and Nio Netty transports expected to be supported and covered with unit test (at least in tcp-transport), test dependency on netty-transport-native-epoll artifact should not be mandatory for modules using transport
