refactor: clean up CoreResourceKinds

[AlessandroPomponio]

Context

CoreResourceKinds has entries which aren't used and could be removed to clean it up and reduce the amount of space used in the CLI when listing them.

ado/orchestrator/core/resources.py

Lines 14 to 23 in cd99105

	class CoreResourceKinds(enum.Enum):
	RESOURCE = "resource"
	OPERATION = "operation"
	RESULT = "result"
	DISCOVERYSPACE = "discoveryspace"
	# ACTUATOR = "actuator" AP - REMOVING IT AS REPLACED BY ACTUATORCONFIGURATION
	ACTUATORCONFIGURATION = "actuatorconfiguration"
	OPERATOR = "operator"
	SAMPLESTORE = "samplestore"
	DATACONTAINER = "datacontainer"

Could (as it stands) easily be trimmed down to:

class CoreResourceKinds(enum.Enum):
    OPERATION = "operation"
    DISCOVERYSPACE = "discoveryspace"
    ACTUATORCONFIGURATION = "actuatorconfiguration"
    SAMPLESTORE = "samplestore"
    DATACONTAINER = "datacontainer"
