Title: Plugin Manager should support -remove group/artifact/version naming

When installing a plugin, we use:

```sh
bin/plugin --install groupid/artifactid/version
```

But when removing the plugin, we only support:

```sh
bin/plugin --remove dirname
```

where `dirname` is the directory name of the plugin under `/plugins` dir.

Closes #3421.
