Summary:
This PR implements auto-conversion of GPU arrays that support the `__cuda_array_interface__` protocol (fixes#15601).
If an object exposes the `__cuda_array_interface__` attribute, `touch.as_tensor()` and `touch.tensor()` will use the exposed device memory.
#### Zero-copy
When using `touch.as_tensor(...,device=D)` where `D` is the same device as the one used in `__cuda_array_interface__`.
#### Implicit copy
When using `touch.as_tensor(...,device=D)` where `D` is the CPU or another non-CUDA device.
#### Explicit copy
When using `torch.tensor()`.
#### Exception
When using `touch.as_tensor(...,device=D)` where `D` is a CUDA device not used in `__cuda_array_interface__`.
#### Lifetime
`torch.as_tensor(obj)` tensor grabs a reference to `obj` so that the lifetime of `obj` exceeds the tensor

common.py is used in base_module for almost all tests in test/. The
name of this file is so common that can easily conflict with other dependencies
if they happen to have another common.py in the base module. Rename the file to
avoid conflict.

Summary:
_Implements pytorch/pytorch#11914, cc: ezyang_
Implements `__cuda_array_interface__` for non-sparse cuda tensors,
providing compatibility with numba (and other cuda projects...).
Adds `numba` installation to the `xenial-cuda9` jenkins test environments via direct installation in `.jenkins/pytorch/test.sh` and numba-oriented test suite in `test/test_numba_integration.py`.
