[BAEL-9497] Fix failing context tests - part 1 (#7719)

* fixed context dependency issue and added LiveContext notes in persistence-modules/spring-data-couchbase-2 module

* fixed Context tests and added notes for spring-cloud-bus/spring-cloud-config-client module

* Added context test in spring-cloud-data-flow/spring-cloud-data-flow-stream-processing/data-flow-server module, mainly due to incompatible dependencies, plus fixed parent pom path in different modules

* fixed context tests for spring-cloud/spring-cloud-task/springcloudtaskbatch module, renamed ContextLiveTest as IntegrationTest, now configured to run with an H2 embedded instance. Moved the run note to the application

* Added SpringContextLiveTests in persistence-modules/spring-data-mongodb module
