Review comment:
We already have an endpoint called `/api/cluster/plugin` GET/POST
Please refer to
[SOLR-14404](https://issues.apache.org/jira/browse/SOLR-14404) for details
it can look as follows
```
curl -X POST -H 'Content-type:application/json' --data-binary '
{
"set-assign-strategy": {
"class": "full.ClassName",
"key1" : "val1"
}
}' http://localhost:8983/api/cluster/plugins
```
```
curl -X POST -H 'Content-type:application/json' --data-binary '
{
"set-assign-strategy": null
}' http://localhost:8983/api/cluster/plugins
```
