Add Gradle properties for disabling project's TC integration (#2483)

Use Gradle property no_teamcity_interaction (e.g. gradle -Pno_teamcity_interaction ...) to disable project's TeamCity integration (printing of the library version as build number in this case).

Gradle property build_snapshot_up is also supported.
