/**
 * Service for validating the model of a node.
 * Ideally, this should be done with a JSON schema validator, like ajv, but for our use case, it's not possible,
 * since we need to validate the model against the schema, but also against the definition of the node.
 *
 * TODO: This service should be reshaped as a Manager entity which register many validators, and each validator
 * should be able to validate a specific aspect of the model. This way, we could have a validator for the schema,
 * and another one for the definition.
 *
 * For instance, the schema validator could be used to validate the model against the schema, and the definition
 * validator could be used to validate the model against the definition, and check if the model is complete. In addition to that,
 * we could validate the model against external constraints, like whether a property is defined in an environment variable or a
 * property file.
