use unified project name Cloud Kernel

We had too many names for our projects before, Aliyun Linux Kernel(ALK),
Alibaba Cloud Linux Kernel, Cloud Kernel, etc. Now we have a unified
project name as the "Cloud Kernel". If the company name should appear
if necessary, the name "Alibaba Cloud Kernel" would be used.

-Alibaba Cloud Linux Kernel (ALK), a customized and optimized version of Linux kernel, is originated by Alibaba Operating System Team (formerly known as Taobao Kernel Team). ALK is installed as the default kernel in Alibaba Cloud Linux OS version 2 (a.k.a Aliyun Linux 2), which is running on Alibaba Cloud Elastic Compute Service (ECS) product. In ALK, several features and enhancements adapted to specific Alibaba Cloud infrastructre and products have been made to help Alibaba Cloud customers to achieve better user experiences.

-Like many other kernels, ALK should work with almost all commonly-used Linux distributions, however, we highly recommend you run it in Alibaba Cloud Linux OS with Alibaba Cloud ECS instances to get best functionality, performance and stability.

 ## 2. Getting Started
 
-To use ALK, you may want either to run a pre-built version or to compile it from source codes. Note that the default kernel configuration file is a customized version for Alibaba Cloud ECS instances, you might need to enable specific drivers and re-compile the kernel if you want to run it on non-ECS platforms.
