usages of the module and if necessary introduces replacement classes.

module to establish a clearer boundary between the interface meant for
consumers and interfaces meant for the the serve implementation.

This change increases the logging level from INFO to WARN in order to
reduce the amount of messages printed to the console during tests.

This change updates the Gradle configuration to utilize version
constraints to force the same dependency version across modules.

This change moves the version of the dependencies from buildSrc to
gradle.properties to prevent recompilation when changing dependency
versions.

This change extracts the configuration for test from the Kotlin library
conventions.

This change removes unnecessary dependencies on JUnit Platform launcher
from the repository. Previously, the launcher was used to bootstrap
tests for Gradle when it did not natively support JUnit Platform.

Gradle now has native support for JUnit Platform, so the dependency is
not needed anymore.

This change allows users to select the hypervisor scheduler to use when
deploying hypervisors onto bare-metal machines.

This change updates the workflow service to delegate the resource
scheduling logic to the virtualized resource provisioner.
