Github Branch

As most of the development works are on Kylin 4, we need to switch it as main branch. Apache Kylin community changes the branch settings on Github since 2021-08-04 :

1. The original branch kylin-on-parquet-v2 for Kylin 4.X (Parquet Storage) has been renamed to branch main, and configured as the default branch;
2. The original branch master for Kylin 3.X (HBase Storage) has been renamed to branch kylin3 ;

Please check Intro to Kylin 4 architecture and INFRA-22166 if you are interested.

I am not quite not sure if I need to merge this patch since it is incompatible. I know some Kylin user write program to read and parse the dict tables's file to decode the Bitmap into original literal values. I wonder if this patch may break these user.
