Getting generic resource by ID ignores provider type - returns wrong object

[grnadav]

Hello

When getting a generic resource by Id, it ignores the provider and uses only resource group name and object name, thus when there are 2 (or more) objects with same name (but different provider type) the wrong object is returned (first result?)

Issue is at:

good catch.
[notes to self] GenericResources should not be extending the SupportsGettingByGroup interface. Instead, maybe just expose their own getByGroup which takes provider type as a 3rd param.

PR with the fix created: #1003

fix merged into master.
GenericResources@getByGroup() has been removed.
A new GenericResources@get() overload has been added to identify a recourse using its resource group, name, provider namespace and resource type.
