Refactor deviceTango. Drop inheritance from DeviceProxy

Motivation:

• Old deviceTango is messing up with inheritance from tango.DeviceProxy (https://gitlab.com/tango-controls/pytango/-/merge_requests/430), and it's not meant to be inherited at all.
• Attributes are read in a weird way. Using attribute_history is not efficient, read_attribute must be used in synchronous mode.
• Switch to event subscription mode. It's asynchronous and doesn't block Tango DeviceServer internal processes, which may be a reason for Eiger DS crash at P11.
• Import to Kamzik only necessary commands and attributes, which can be configured in the config section in the YAML file.
