There are now four families of FE builds:

- `build` does a one-shot dev build.
- `build-watch` watches for changes and does dev rebuilds; no server.
- `build-hot` is `build-watch` plus a development web server.
- `build-release` is a one-shot release mode build.

Each family has `:cljs` and `:js` variants, to build just one part.

* MLv2: Add `display-name` style parameter with `:default` and `:long` options

* Add test for #29947

* Fix typos

* Update JS unit tests

* initial changes

* add saml api

* address changes

* git restore enterprise/backend/test/metabase_enterprise/sso/api/saml_test.clj

* update comment

* update to have /api

* remove dbg

* fix alias

* change deps

* update test

* add test

* update test

* split tests

* add paren

* [MLv2] Remove and replace fields clause

* Add docstring

* Delete old persistence schemas in redshift

Reminder that recently a change occurred that populates a cache_info
table in each persisted schema:

```sql
-- postgres/redshift
test-data=# select * from metabase_cache_424a9_379.cache_info ;
       key        |                value
------------------+--------------------------------------
 settings-version | 1
 created-at       | 2023-03-29T14:16:24.849866Z
 instance-uuid    | 407e4ba8-2bab-470f-aeb5-9fc63fd18c4e
 instance-name    | Metabase Test
(4 rows)
```

So for each cache schema, we can classify it as
- old style (a commit before this change. more and more infrequent)
- new style recent
- new style expired

And we can delete them accordingly in startup:
```
2023-04-11 20:09:03,402 INFO data.redshift :: Dropping expired cache schema: metabase_cache_0149c_359
2023-04-11 20:09:04,733 INFO data.redshift :: Dropping expired cache schema: metabase_cache_0149c_70
2023-04-11 20:09:05,557 INFO data.redshift :: Dropping expired cache schema: metabase_cache_0149c_71
2023-04-11 20:09:06,284 INFO data.redshift :: Dropping expired cache schema: metabase_cache_0149c_90
...
2023-04-11 20:20:33,271 INFO data.redshift :: Dropping expired cache schema: metabase_cache_fe4a7_90
2023-04-11 20:20:34,284 INFO data.redshift :: Dropping old cache schema without `cache_info` table: metabase_cache_8f4b8_358
2023-04-11 20:20:35,076 INFO data.redshift :: Dropping old cache schema without `cache_info` table: metabase_cache_8f4b8_69
...
```

It's possible this will at first cause a few flakes if we are unlucky
enough to drop a cache schema without `cache_info` for an instance that
is running tests at that point. But the `cache_info` table has been
backported so the chances of that become smaller each day.

I've let a week elapse from that change before committing this so
hopefully it is not an issue in practice.

Number of queries:
Makes a single query to get all schemas, then for each schema makes a
query to classify it. This can be unified into a single query with some
shenanigans like

```clojure
(sql/format {:select [:schema :created-at]
             :from   {:union-all
                      (for [schema schemas]
                        {:select [[[:inline schema] :schema]
                                  [{:select [:value]
                                    :from   [(keyword schema "cache_info")]
                                    :where  [:= :key [:inline "created-at"]]}
                                   :created-at]]})}}
            {:dialect :ansi})
```

But i found that this query is extremely slow and does not offer any
benefit over the simpler, repeated queries. And as we run this on each
commit now, the number of schemas will be far lower and it will be on
the order of 5-10 schemas (and therefore queries) and therefore not an
issue.

* Ngoc's suggestions

- docstring for `delete-old-schemas!`
- combine nested `doseq`
- use java-time over interop with java.time

* Build experimental multi-arch docker image (partially #13119)

* Fix `type-of` calculation for `:power` clauses

* Test fix 

* makes sure serdes can find and handle toucan2 models

Using SqlFormatter config to prevent incorrect expansion of metabase parameters when formatting.

Better metabot logging, especially around generated token counts. This will be particularly useful as we determine what size of prompts we can generate.

This reverts commit 8a11e382.

The namespace `metabase.server.middleware.security` controls our content
security policy header. In dev we allow connections to 8080 for webpack
assets. Not dev we deny these.

`clj -M:run` is dev since it is running the project from source, not a
jar. This `mb.run.mode` was removed when we were fighting require issues
for `metabase.query-processor-test.test-mlv2`. That's solved so we can
restore the dev property to `:run`.

* MLv2: fix join `:fields` conversion (#29898)

* Remove test skip rule

Fixed missing seed {} in a reduce and added tests.

in query_processor.clj we were requiring

```clojure
(when-not config/is-prod?
  (classloader/require 'metabase.query-processor-test.test-mlv2))
```

And this was blowing up as it was not present in the aliases used for
cypress and the FE crew.

Now user.clj requires it in the same way that it requires
`[metabase.test-runner.assert-exprs]` so we can run tests with
`partial=` and their ilk. And it is required by the test entry namespace
so CI and test runners find it as well.

The `resolve` command in query_processor.clj now works in dev and CI

```clojure
query-processor=> (resolve 'metabase.query-processor-test.test-mlv2/post-processing-middleware)
,#'metabase.query-processor-test.test-mlv2/post-processing-middleware
```
(comma to prevent commit message from eliding as a comment)

so presumably tests that require the middleware tricks from this test
namespace will continue to work.
