feat: init and get command support json format output

[Ericwww]

Resolves #1373

In init or get package, lots of output is calling method on cli.UI interface

If you want to output in JSON, you should call method on views.JSONView.

I tried to draw a figure to explain the logical here. (the green color is some logical I added in this PR.)

I create a wrappedUI and implement the cli.UI interface. It contains jsonView and cli.UI in it.

If -json is given, wrappedUI will call the method on jsonView. If not, wrappedUI will call the method on cli.Ui, be consistent with current logical.

Read Before Review

At present, the logic of -json is simply implemented. If you look carefully, there are actually a lot of details that could be better.

For example, in output like the following, characters like \n should not appear in theory.

But in order to ensure that the previous display information is not changed too much, I can only accept this situation for the time being.

If you have any objections to this, you are welcome to raise it and I will find a way to continue to solve it.

In addition, I also found an issue from hashicorp/go-hclog.

When the information to be output contains some special characters, such as &, >, < and other symbols, the output will be escaped.

I have submitted issues and PRs to this repository, but have not received any feedback yet.

Well, hashicorp merged my PR and release a new version. I will fix the problem I mentioned above.

It seems OK now.
