Roy Wetherall 8a0dc74bca Support for linking and unlinking rules.
- Link and unlink actions avaible to allow one rule node to reuse the rule set from another rule set.
- Methods added to rule service API to get information about linked to and linked from rule nodes.

Note: 
- The action execution queue REST API can be used to call the link and unlink actions.
- The rule set REST API needs to be extended to provid information about what links to and from a rule node.
