In order to cooperate with Doris's successful graduation from Apache, the Doris official website also needs a new look
and more powerful feature, so we decided to redesign the Doris official website.
The code and documents of the new official website are included in this PR.
Since the new website is completely rewritten, the content and structure of the project are different from the previous one.
In particular, the directory structure of documents has changed, and the number of documents is large, so the number of
files in this PR is very large.
In the old website，all English documents are in the en/ directory, and Chinese documents in the zh-CN/ directory,
but in the new website，the documents are split into multiple directories according to the nav.
The document's directory structure changes as follows：
```
docs (old website)
| |—— .vuepress (library)
| |—— en
| | |—— admin-manual
│ │ |—— advanced
| | |—— article
| | |—— benchmark
| | |—— case-user
| | |—— community
| | |—— data-operate
| | |—— data-table
| | |—— design
| | |—— developer-guide
| | |—— downloads
| | |—— ecosystem
| | |—— faq
| | |—— get-starting
| | |—— install

Currently, only the root user has node_priv privileges.
That is, only the root user can operate the addition and deletion of nodes.
In the original design of Doris, there is an Operator role. This role can have node_priv for node operations.
This PR supports assigning node_priv to users other than root.
However, only users who have both grant_priv and node_priv can assign node_priv to other users.
This ensures that only the root user has this permission, and users who are given node_priv
cannot continue to expand this permission outward.
This CL mainly changes:
1. Broker Load
When assigning backends, use user level resource tag to find available backends.
If user level resource tag is not set, broker load task can be assigned to any BE node,
otherwise, task can only be assigned to BE node which match the user level tags.
2. Routine Load
The current routine load job does not have user info, so it can not get user level tag when assigning tasks.
So there are 2 ways:
1. For old routine load job, use tags of replica allocation info to select BE nodes.
2. For new routine load job, the user info will be added and persisted in routine load job.
