[vandyliu]

we will need to require these query params

	type getClusterOptionsQueryParams struct {
		Provider string `form:"provider" binding:"omitempty,oneof=AWS AZURE GCP" enums:"AWS,AZURE,GCP"`
		Type     string `form:"type" binding:"required,oneof=HYBRID DEDICATED" enums:"HYBRID,DEDICATED"`
	}
