test(spring-boot): Move the Boot 2 OTel agent sample's tests into the module

Adds the agent setup to sentry-spring-boot, as in the Boot 3 and 4
modules. The sample's tests were the Boot 3 agent sample's minus Cache
and RestClient, which Boot 2 doesn't have. GraphQL and Kafka are gated
on Boot 2.7, as in the other Boot 2 suites.

The shared app has to start on Boot versions without Kafka support, so
the Kafka test starts an app of its own with the kafka profile and an
in-JVM broker. AgentApp becomes a class for that, with the shared
instance in its companion.

The sample has no system tests left, so it comes off the system-test
runner, the backend workflow and the Spring Boot 2 matrix, which now
runs both agent tasks and no longer builds the agent separately.
integrationTests includes them too.
