/**
 * [ Why need OperantsManager? ]
 *
 * Ideally, overloading tensor operators should call Tensor API directly.
 * However, we faced two problems:
 *
 * 1. Support multiple modes: Tensor operator overloading needs to support
 * [static mode / autograd mode / custom operator mode] at the same time.
 *
 * 2. Decouple phi and fluid: Tensor belongs to the phi library, but it relies
 * upon functions in fluid when overloading Tensor operators.
 *
 * We design OperantsManager to solve these two problems:
 *
 * 1. use `FLAGS_tensor_operants_mode` to handle overloading mode, set this flag
 * at the entry point of each mode:
 *
 * - FLAGS_tensor_operants_mode = "static": at the construction function of
 * `CompositeGradOpMakerBase`.
 * - FLAGS_tensor_operants_mode = "eager": at the beginning of dygraph_function.
 * - FLAGS_tensor_operants_mode = "phi": at the beginning of the
 * `eager_api_run_custom_op` function in eager mode and at the beginning of
 * calling kernels in static mode.
 *
 * In order to guarantee the performance, OperantsManager holds three pointers
 * to identify each mode respectively.
 *
 * 2. Decouple phi with the help of the polymorphism mechanism,
 * TensorOperantsBase derives three child classes: PhiTensorOperants,
 * EagerTensorOperants, and StaticTensorOperants. We set eager and static tensor
 * operants at the fluid library and set phi operants at the phi library.
 *
