* bumps outdated deps versions to be current

* un-upgrade h2 and jetty

* un-upgrade joda-time and kixi/stats

* drop Java 8 support in circle CI config

- things that used to rely on be-tests-java-8-ee now rely on be-tests-java-11-ee

* remove java 8 from github health check matrix

* revert toucan to 1.17.0

* revert mariadb java client to 2.7.5

* Back to 18, and handle new behavior

toucan used to just look in *.models.<model-name> for models and just
give up apparently. I made a feature that toucan will look in a model
registry to create models rather than using the convention
https://github.com/metabase/toucan/commit/762ad69defc1477423fa9423e9320ed318f7cfe7


but now we're getting errors in these tests about maps vs models.

```clojure

                                                      :message nil,
                                                      :diff
                                                      {:o1 nil,
                                                       :o2
                                                       #metabase.models.revision_test.FakedCardInstance{:name
                                                                                                        "Tips Created by Day",
                                                                                                        :serialized
                                                                                                        true}}})
```

The only difference here is `:o2` is a
`metabase.models.revision_test.FakedCardInstance` but still has the same
keys, `:name`, and `:serialized`. So all is well, we're just able to
make the model.

So a few different fixes. Some are use `partial=` which doesn't care
about record/map distinction. Some are just make the model, and some are
turning them into maps for revision strings (which more closely mimics
what the real revision stuff does):

```clojure
(defn default-diff-map
  "Default implementation of `diff-map` which simply uses clojures `data/diff` function and sets the keys `:before` and `:after`."
  [_ o1 o2]
  (when o1
    (let [[before after] (data/diff o1 o2)]
      {:before before
       :after  after})))

(defn default-diff-str
  "Default implementation of `diff-str` which simply uses clojures `data/diff` function and passes that on to `diff-string`."
  [entity o1 o2]
  (when-let [[before after] (data/diff o1 o2)]
    (diff-string (:name entity) before after)))
```

So all in all this change impacts nothing in the app itself, because
those models follow convention and are correct in
`metabase.models.<model-name>` and are thus "modelified":

```clojure
revision-test=> (revision/revisions Card 1)
[#metabase.models.revision.RevisionInstance{:is_creation true,
                                            :model_id 1,
                                            :id 1,
                                            :is_reversion false,
                                            :user_id 2,
                                            :timestamp #object[java.time.OffsetDateTime

                                            :object #metabase.models.card.CardInstance
                                            {:description nil,
                                             :archived false,
                                             :collection_position nil,
                                             :table_id 5,

                                             :collection_id nil,
                                             :query_type :query,
                                             :name "ECVYUHSWQJYMSOCIFHQC",
                                             :creator_id 2,
                                             :made_public_by_id nil,
                                             :embedding_params nil,
                                             :cache_ttl 1234,
                                             :dataset_query {:database 2,
                                                             :type :query,
                                                             :query {:source-table 5,
                                                                     :aggregation [[:count]]}},
                                             :id 1,
                                             :display :scalar,
                                             :visualization_settings {:global {:title nil}},
                                             :dataset false,
                                             :public_uuid nil},
                                            :message nil,
                                            :model "Card"}]
```

so the model/no-model is just arbitrary distinction in the test. All of
them in the actual app are turned into models:

```clojure
(defn- do-post-select-for-object
  "Call the appropriate `post-select` methods (including the type functions) on the `:object` this Revision recorded.
  This is important for things like Card revisions, where the `:dataset_query` property needs to be normalized when
  coming out of the DB."
  [{:keys [model], :as revision}]
  ;; in some cases (such as tests) we have 'fake' models that cannot be resolved normally; don't fail entirely in
  ;; those cases
  (let [model (u/ignore-exceptions (db/resolve-model (symbol model)))]
    (cond-> revision
    ;; this line would not find a model previously for FakedCard and
    ;; just return the map. But now the registry in toucan _finds_ the
    ;; model defintion and returns the model'd map
      model (update :object (partial models/do-post-select model)))))

(u/strict-extend (class Revision)
  models/IModel
  (merge models/IModelDefaults
         {:types       (constantly {:object :json})
          :pre-insert  pre-insert
          :pre-update  (fn [& _] (throw (Exception. (tru "You cannot update a Revision!"))))
          :post-select do-post-select-for-object}))
```
