     * These property group is used to build kotlinx.coroutines against Kotlin compiler snapshot.
     * How does it work:
     * When build_snapshot_train is set to true, kotlin_version property is overridden with kotlin_snapshot_version,
     * atomicfu_version is overwritten by TeamCity environment (AFU is built with snapshot and published to mavenLocal
     * as previous step or the snapshot build).
     * Additionally, mavenLocal and Sonatype snapshots are added to repository list and stress tests are disabled.
     * DO NOT change the name of these properties without adapting kotlinx.train build chain.
