Normalize directories and generate redirections (#315)

Some structure changes:

 - `api/api-reference/controller-xxx` => `api/controllers/xxx`
 - `guide/guides/xxx` => `guides/xxx`
 - `plugins/plugins/xxx` => split entre `plugins/guides/xxx` et `plugins/essentials`
 - `protocols/protocols/xxx` => split entre `protocols/api/xxx`, `protocols/essentials/xxx` et `protocols/native-protocols/xxx`

JS 5, PHP 3 and Android 3 SDK are now on the same structures as the other SDK (`core-classes`, `essentials`)
 
The file [redirections.yml](https://github.com/kuzzleio/documentation/blob/d237e73ee394b23ccfaf34ce7bf36c1078a402ae/redirections.yml) contain all the redirection from the old v2 pages to new v3 pages.  
Paths like `api/1/controller-document` are root path, redirection for files in subfolders has to be handled.  

The script `check_redirections.rb` checks that every page from v2 has a redirection in v3.

I also replace every links after renaming/moving directories. (Maybe I miss some links but Vuepress have a dead link checker)

 VuePress generates the documentation based on how the files are organized in the filesystem. For example, the URL of each page is direclty infered by its filesystem path relative to `src/`. Also, the left sidebar generation is based on the filesystem location of the files and their [frontmatter](https://v1.vuepress.vuejs.org/guide/frontmatter.html#front-matter) contents.

 If you want to avoid downloading the SDK each time you run a snippet, you can use the following variable:
 
 ```bash
 export DEV_MODE=true

-bash run-snippet-tests.sh -n -p src/sdk-reference/cpp/1/index
+bash run-snippet-tests.sh -n -p src/sdk/cpp/1/controllers/index

 ### Writing tests
 
 To make a snippet testable, simply create a YML file called `<snippet-name>.test.yml` along with the snippet file, like the following:
