Seaweedfs 3.18 发布

You can now setup a production-ready SeaweedFS S3 on AWS with cloudformation to enjoy the fastest S3 API, and support SeaweedFS!

The 3.17 has a bug that adds a 150ms sleep during each file read operation. It is deleted and here is the same release notes from 3.17.

This release solved 2 major problems:

1. When a master is down, the masters will elect a new leader and the volume servers will report itself to the new leader. This process will take many seconds. During this time, volume id lookup can fail. This is solved in #3350 by reusing previous maps.
2. weed mount fixed wrong logic about hard links.

• Volume Server
