MINOR: Cleanup Trogdor Module

[sjhajharia]

Now that Kafka support Java 17, this PR makes some changes in trogdor
module. The changes mostly include:

• Collections.emptyList(), Collections.singletonList() and Arrays.asList() are replaced with List.of()
• Collections.emptyMap() and Collections.singletonMap() are replaced with Map.of()
• Collections.singleton() is replaced with Set.of()

Some minor cleanups around use of enhanced switch blocks and conversion of classes to record classes.

Thank you @m1a2st and @Pankraz76 for the reviews. I have addressed them.
Requesting a re-review when possible.
TIA!

nicely done, thanks. Until taken care by plugin it can happen anytime leaving this task kind of open. Offering to apply thins kind of conventions via rewrite.

Adding @chia7712 for review
TIA.

the name taskId is same as the method name, so are those annotations really necessary?

[Pankraz76]

considering Override kind of best practice, it should not do any harm.

Can not tell anything about JsonProperty, except of assuming its needed by the business case, therefore covered by some test, or it can be removed/challenged.
