[WFCORE-6503]:Add support for unmanaged deployments with YAML extension.

* checking that the YAML deployment is unmanaged.
* adding the unmanaged deployment to the list of operations
* adding some light esting on this
* adding WARNING traces
* adding warning if YAML is adding an existing resource without any attribute
* failing if unexisting attribute is used
* better error messages
* ignoring removal of unexisting resource
* warning about ignoring unexisting resource delete operation
* Fixing how we apply YAML configuration on reload
* Adding configuration for YAML file size.
* Adding tests for yaml
