[pve-devel] [PATCH dart_api_client 2/4] Add int serializer to handle string values

[Aaron Lauterer]

Adding a custom serializer for integers, allows us to handle situations
in which the PVE API provides the values in other types. For now, the
most likely situation is that the API formats the JSON value as string
instead of a number, therefore we try to catch that and parse it as int.
