Hello,

What does the columns `type` and `isolation` mean in the `cat plugins` output.

Also why do some plugins show `url` and some don’t.

```

Some plugins have site feature (will be removed in next major version though).

Type means jvm and or site plugin (will be removed)

Isolation means that the classloader of a plugin should not see other plugins classloader. Only applies to jvm plugins.

Type is either site or jvm. Site plugins are just elasticsearch being a  
simple web server. Jvm plugins change the behavior. Isolation = false is a  
hack to let plugins communicate with one another. It means they aren't in  
their own classloader. It's discouraged/deprecated.
