[BUG]: Missing copyright notices and licenses

[groganz]

🐛 Describe the bug

Following best practices, all projects under https://github.com/hpcaitech should have a LICENSE file and all source code should include a copyright notice.

These projects lack a LICENSE file:

https://github.com/hpcaitech/CachedEmbedding https://github.com/hpcaitech/OPT-Benchmark https://github.com/hpcaitech/ColossalAI-Pytorch-lightning https://github.com/hpcaitech/luchen-website https://github.com/hpcaitech/TensorNVMe

The copyright notice should be added in the LICENSE file of each project, e.g. at https://github.com/hpcaitech/ColossalAI/blob/main/LICENSE#L190, presumably:

Copyright 2021- HPC-AI Technology Inc.

It should also be added on top of each source code file by including the appropriate source header also including the respective license information, e.g.

# Copyright 2021- HPC-AI Technology Inc.
#
# Licensed under the Apache License, Version 2.0 (the "License");
# you may not use this file except in compliance with the License.
# You may obtain a copy of the License at
