/**
* This feature enables logging request and/or response on client-side and/or server-side depending
* on the context's {@link RuntimeType}.
*
* The feature may be register programmatically like other features by calling any of {@link javax.ws.rs.core.Configurable}
* {@code register(...)} method, i.e. {@link javax.ws.rs.core.Configurable#register(Class)} or by setting any of the
* configuration property listed bellow.
*
* Common configurable properties applies for both client and server and are following:
*
* - {@link #LOGGING_FEATURE_LOGGER_NAME}
* - {@link #LOGGING_FEATURE_LOGGER_LEVEL}
* - {@link #LOGGING_FEATURE_VERBOSITY}
* - {@link #LOGGING_FEATURE_MAX_ENTITY_SIZE}
* - {@link #LOGGING_FEATURE_SEPARATOR}
*
*
* If any of the configuration value is not set, following default values are applied:
*
* - logger name: {@code org.glassfish.jersey.logging.LoggingFeature}
* - logger level: {@link Level#FINE}
* - verbosity: {@link Verbosity#PAYLOAD_TEXT}
* - maximum entity size: {@value #DEFAULT_MAX_ENTITY_SIZE}
*
*
* Server configurable properties:
*
* - {@link #LOGGING_FEATURE_LOGGER_NAME_SERVER}
* - {@link #LOGGING_FEATURE_LOGGER_LEVEL_SERVER}
* - {@link #LOGGING_FEATURE_VERBOSITY_SERVER}
* - {@link #LOGGING_FEATURE_MAX_ENTITY_SIZE_SERVER}
* - {@link #LOGGING_FEATURE_SEPARATOR_SERVER}
*
* Client configurable properties:
*
* - {@link #LOGGING_FEATURE_LOGGER_NAME_CLIENT}
* - {@link #LOGGING_FEATURE_LOGGER_LEVEL_CLIENT}
* - {@link #LOGGING_FEATURE_VERBOSITY_CLIENT}
* - {@link #LOGGING_FEATURE_MAX_ENTITY_SIZE_CLIENT}
