Support additional Atera device type endpoints

Please add support for the following Atera API endpoints so all device types can populate in Hudu sort rules:

GET /api/v3/devices/genericdevices

GET /api/v3/devices/tcpdevices

GET /api/v3/devices/httpdevices

Currently, only GET /api/v3/agents and GET /api/v3/devices/snmpdevices appear to be supported.
