Arthas: Support html view for WebUI

[kylixs]

At present, a simple WebUI is implemented based on http api, which can only display json data and is not suitable for human reading. We need a text / html view to better display the results of command interaction. It expects to provide a modern operating experience, richer functions, and more flexible scalability.

Build
The http api code will be divided into multiple PRs and merged into the master, which can now be tested and improved on the feature branch.

1. Checkout termd project, build and install to local repo.

   cd /path/projects/
   git clone https://github.com/alibaba/termd.git
   mvn clean install -Dmaven.test.skip -DskipTests

1. Checkout the source code of http api, build and package.

   cd /path/projects/
   git clone https://github.com/alibaba/arthas.git
   git checkout http-api
   mvn clean package

    cd /path/projects/arthas

The error details: Failed to delete .../arthas/spy/target/maven-archiver/pom.properties
1) Please stop the Arthas that have been injected;
2) Check what process opened the file spy / target / maven-archiver / pom.properties, please close it. You can use the Process Hacker / Process Explorer tool to find the file handle to discover the process of opening the file.
3) Or just restart the system and rebuild.

Yes, the first stage of development is completed and is gradually being merged into the master.
Now you can contribute code, if accepted, it will eventually be merged into the master, but it will take a while.
