+/**
+ * This activator is used to initialize and terminate the connection pool to one or more providers.
+ * <p>
+ * The CDP abstraction layer supports multiple types of providers, with each provider supporting multiple tenants. The
+ * "connection" to a specific tenant on a specific provider is represented by a "context" object. These context objects
+ * are authenticated to a specific tenant on the provider, but can be reused from one request to another. Contexts are
+ * slow to set up and are resource intensive, so they are cached. However, the contexts for a specific tenant on a
+ * specific provider must be cached separately.
+ * </p>
+ * <p>
+ * Activation of the bundle creates an empty cache which is organized first by provider type, then by tenant name, with
+ * the contents being an empty pool of contexts for that provider/tenant combination. The pool is created on first use,
+ * and retained for as long as the bundle is active.
+ * </p>
+ * <p>
+ * When the bundle is deactivated, the cache is torn down with all contexts being closed.
