Create a version in the ITS based on an event property value
create-version-from-property is a new type of action named ProjectAction.
This type of actions are triggered on the same events but don't require a matching issue
to be executed.
A ProjectAction requires an association to be set between a Gerrit project and
its ITS counterpart in order to know on which ITS project the action
must be performed.
create-version-from-property can be used to create a version in the ITS project
when a Tag is created in the Gerrit project.
