Currently, properties cannot be searched in some workspaces, like `configuration`.

User story:

As an administrator, I want to find the "defaultBaseUrl" property in the Configuration app.

As a developer, I want to find all field definitions where the class property is set to info.magnolia.ui.form.field.definition.StaticFieldDefinition

Regression. Searching for defaultBaseUrl worked in Magnolia 5. You get the parent node and can navigate to the property with couple of clicks. In Magnolia 6 you cannot find it.

Acceptance criteria:

• Magnolia 5 in-app search capabilities should be ported to periscope, that is:
  • Searching for property names should find those, e.g. searching for defaultBaseUrl should list config's /server@defaultBaseUrl as result (or its containing node).
  • Searching for property values should find that property as well, e.g. searching for -ResourcesServlet-  info.magnolia.module.resources.ResourcesServlet should list config's /server/filters/servlets/ResourcesServlet@servlet-Name-Class as result (or its containing node).
• Add property search for config workspace only.
• Create a configuration for setting property search on/off.
