juju#18485

The pruner workers for status history and actions will not exist in their current form under Dqlite.

They are removed, along with their clients, APIs, state logic and tests.

```sh
$ juju bootstrap lxd test
$ juju add-model default
$ juju deploy ubuntu
$ juju remove-application ubuntu --force
```
