[DNF5] Allow to install multiple object types (rpm/group/modules) in one transaction

[j-mracek]

For install command in DNF4 we use @ to mark arguments which represents group, env. group or modules. Then we search in modules, and group and the first matched object is used. It means noane is able to install minimal group when minimal module exists. The name collision appears more often when user is using repositories from multiple resources.

For DNF5 we should find a way how to handle it with exact definition whether we are going to install module, group or env. group.
