GEODE-5883: Add Nebula dependency linter as gradle utility (apache#2939)

* Introduce Nebula lint plugin, version 10.1.0
* Update Nebula project plugin version 4.0.1 -> 5.1.0
* Update gradle-git plugin version 1.3.2 -> 1.7.2

* The lint plugin is intentionally not yet run as part of the project :check.
Early introduction will be required by some subprojects,
so that they may reference the plugin configuration.
