Merge-strategy for included config files must now be
specified as yaml map of the form:
- path: foo
strategy: bar
If `strategy` is omitted, or the old `string-only` form is used,
`append` strategy is enforced.

By default we now use the `append` merge-strategy:
* existing sequence keys will be appended
* existing scalar keys will be overridden
* non-existing keys will be added
We also have an `override` merge-strategy:
* existing keys will be overridden
* non-existing keys will be added
Finally, there is an `add-only` merge-strategy:
* existing keys will be ignored
* non-existing keys will be added

Also, moved yaml_helper under engine/ folder.
Ported rule json schema validation in the engine.
Also, updated rule_loader tests to check for validation.
