/**
 * The internal configuration loader for the package. Used by the package's
 * service provider.
 *
 * This package provides developers three ways to configure it: through the
 * environment, by adding config values to the configuration for the other
 * components that the package wraps, and by creating an external package
 * configuration file that overrides the default internal configuration.
 * The package uses its configuration information to set Redis connection,
 * cache, session, and queue configuration values when these are missing.
 * This approach simplifies the code needed to configure the package for many
 * applications while still providing the flexibility needed for advanced
 * setups. This class reconciles each of the configuration methods.
 *
 * The package's configuration contains partial elements from several other
 * component configurations. By default, the package removes its configuration
 * after merging the values into each of the appropriate config locations for
 * the components it initializes. This behavior prevents the artisan CLI's
 * "config:cache" command from saving unnecessary configuration values to the
 * configuration cache file. Set the value of "redis-sentinel.clean_config" to
 * FALSE to disable this behavior.
 *
 * To support these configuration scenarios, this class follows these rules:
 *
 *   - Values in application config files ("config/database.php", etc.) have
 *     the greatest precedence. The package will use these values before any
 *     others and will not modify these values if they exist.
 *   - The package will use values in a developer-supplied package config file
 *     located in the application's "config/" directory with the filename of
 *     "redis-sentinel.php" for any values not found in the application's
 *     standard configuration files before using it's default configuration.
 *   - For any configuration values not provided by standard application
 *     config files or a developer-supplied custom config file, the package
 *     uses it's internal default configuration that reads configuration values
 *     from environment variables.
 *   - The package will copy values from it's configuration to the standard
 *     application configuration at runtime if these are missing. For example,
 *     if the application configuration doesn't contain a key for "database.
 *     redis-sentinel" (the Redis Sentinel connections), this class will copy
 *     its values from "redis-sentinel.database.redis-sentinel" to "database.
 *     redis-sentinel".
 *   - After loading its configuration, the package must only use configuration
 *     values from the standard application config locations. For example, the
 *     package will read the values from "database.redis-sentinel" to configure
 *     Redis Sentinel connections, not "redis-sentinel.database.redis-sentinel".
