Provide shared library which extended functionality lockable-resources-plugin as a groovy code.
The goal is to extend plugin functionality in simple way and provide a solution for end-user with much more then one lock() step. Many users has own solutions to create resources, or check is isFree() ... and are done by interacting with origin Java code. This might hard to make changes here, because nobody can grant, that it works for end-user instances.
In this case we can provide more functionality and customizing as well (edit some groovy lib in forked repo is much more ease then edit Java code and build the plugin self)
