/**
 * This file contains only configuration data such as constants.
 * You can override these constants by defining them BEFORE you including
 * any of the top-level files from the SDK.
 *
 * Definitions:
 * * RAXSDK_TIMEZONE - the default timezone for interpreting date/time requests
 * * RAXSDK_STRICT_PROPERTY_CHECKS - if TRUE, the library will strictly enforce
 *      property names on objects; only properties that are pre-defined or
 *      appear in the extensions aliases for the service will be permitted.
 *      When FALSE (the default), then any property can be set on an object.
 * * RAXSDK_COMPUTE_NAME - the default name for the compute service
 * * RAXSDK_COMPUTE_REGION - the default region for the compute service
 * * RAXSDK_COMPUTE_URLTYPE - the default URL type for the compute service
 * * RAXSDK_OBJSTORE_NAME - the default name for the object storage service
 * * RAXSDK_OBJSTORE_REGION - the default region for the object storage service
 * * RAXSDK_OBJSTORE_URLTYPE - the default URL type for the object storage
 *      service
 * * RAXSDK_DATABASE_NAME - the default name for the DbService service
 * * RAXSDK_DATABASE_REGION - the default region for the DbService service
 * * RAXSDK_DATABASE_URLTYPE - the default URL type for the DbService service
 * * RAXSDK_CONNECTTIMEOUT - the time (in seconds) to wait for a connection
 *      to a service
 * * RAXSDK_TIMEOUT - the max time (in seconds) to wait for an HTTP request
 *      to complete
 * * RAXSDK_SERVER_MAXTIMEOUT - the max time (in seconds) that a server
 *      will wait for a change in status (Server::WaitFor() method)
 * * RAXSDK_POLL_INTERVAL - how often (in seconds) the Server::WaitFor() method
 *      will poll for a status change
 * * RAXSDK_DEFAULT_IP_VERSION - the default IP version (4 or 6) to return for
 *      the server's primary IP address
 * * RAXSDK_OVERLIMIT_TIMEOUT - the max time (in seconds) to wait before
 *      retrying a request that has failed because of rate limits. If the
 *      next available time for the request is more than (X) seconds away,
 *      then the request will fail; otherwise, the request will sleep until
 *      available.
