Allow declaring exclusive resources for child nodes

[vdmitrienko]

Issue: #3102

Overview

Allow declaring "shared resources" for direct child nodes via the new @ResourceLock(target = CHILDREN) attribute.

Using the @ResourceLock(target = CHILDREN) in a class-level annotation has the same semantics as adding an annotation with the same value and mode to each test method and nested test class declared in this class.

This may improve parallelization when a test class declares a READ lock, but only a few methods hold a READ_WRITE lock.

Thank you for your contribution, @vdmitrienko! 👍

After merging, I noticed that the tests were in the wrong package/project so I moved them in c1a976e.
