Issue: RuntimeError: CUDAPluggableAllocator does not yet support cacheInfo
Labels: feature,triaged,module: CUDACachingAllocator

### 🐛 Describe the bug

Here, I ref a third party CUDA Memory Allocator into my code and use the cudnn to be the backend.
cudnn seems required to call `cacheInfo`, but the PyTorch didn't support this interface to be called by third party lib.

cudnn's action happens at here: https://github.com/pytorch/pytorch/blob/9af82fa2b86fb71df503082b1960c9392f9dc66d/aten/src/ATen/native/cudnn/Conv_v7.cpp#L212

```python
import torch
import rmm
from rmm.allocators.torch import rmm_torch_allocator

torch.backends.cudnn.benchmark = True
rmm.reinitialize(pool_allocator=True)
torch.cuda.memory.change_current_allocator(rmm_torch_allocator)

m = torch.nn.Conv1d(16, 33, 3, stride=2).cuda()
input = torch.randn(20, 16, 50).cuda()
output = m(input)
```
