v10.0.0a1

[leofang]

Notes:

1. I removed CUDA 9.2 support for the rc branch to reflect the upcoming change ([RFC] [v10] Dropping Support for CUDA 9.2 & NCCL 2.4 cupy/cupy#5120).
2. ppc64le is enabled, but for CUDA 10.2 only due to cos8 limitation (CentOS 8 conda-forge.github.io#1432)

Oops, the satellite packages are not ready for ppc64le yet...Let me revert the change and move it to a separate PR.
