Convert lettuce-5.0 tests from groovy to java

[jaydeluca]

Related to #7195

Notes:

• I had to modify the assertions in LettuceSyncClientTest.testConnectException() slightly because the groovy test references a class directly that is not accessible in java (io.netty.channel.AbstractChannel.AnnotatedConnectException)
• I created a helper method to handle provisioning the containers and connections for the individual tests that require them. I am using the cleanup extension to defer the closing of the connection, and then also using try with resources in the individual tests. If this seems redundant let me know and I can remove one of them.

usually we use

assertThat(future.get(10, TimeUnit.SECONDS)).isEqualTo(defaultVal));
