Application should not fail if no hadoop binaries are on the classpath

[kevinwallimann]

Description

Currently, the application fails with the following error, when no hadoop-binaries are no the classpath

	Caused by: java.lang.IllegalStateException: Failed to introspect Class [za.co.absa.hyperdrive.trigger.api.rest.services.HyperdriveOffsetComparisonServiceImpl] from ClassLoader [ParallelWebappClassLoader

This happens, even if scheduler.executors.enableHyperdriveExecutor is set to false.

Expected behaviour

If scheduler.executors.enableHyperdriveExecutor is set to false, no such exception should be thrown, as the functionality is disabled anyway and hadoop-binaries are not needed in that case.
