Allow hashes in Combination/Choice module overload
Currently, there doesn't seem to be a way to override a hash-valued parameter in a Combination module.
For instance, if I want to have two different LDAP servers, each returning a different set of attributes :
This currently doesn't work, instead, all attributes from both LDAP servers must be defined on the shared LDAP module configuration, but this is not very flexible and might lead to conflicts.
Maybe allowing JSON in that field?
