Add "Shared Objects" in configuration
Add a section in the main configuration and in templates where "shared objects" can be defined.
The use-case here is to define several layers in the shared objects configuration section and when a client makes a request the client can simply choose the layers by id (rather than define the full layer definition).
An implementation proposal is as follows:
Add to both Configuration and Template a shared section.
In the Values object's populateFromAttributes method, when the attribute value (resolved from either the json or default yaml) is wrapped with {{key}} then use the "key" to look up a shared object first in the template shared objects and then in the Configuration shared objects. If no shared object is found then leave the unresolved.
Can it be a place where we can configure the !configureHttpRequests for all the template ?
