sync the attached datawarehouse (#49970) (#50035)

* sync the attached datawarehouse

requires either "sync_db" true or a table name

it will error
```shell
❯ http post 'localhost:3000/api/notify/db/attached_datawarehouse' x-metabase-apikey:apikey -pb
Must provide `sync_db` or a `table_name` to sync
```

It will sync the db when sync_db is true [NOTE: this is outdated. now just omitting the table name will sync the db]
```shell
❯ echo '{"synchronous?": true, "sync_db": true}' | http post 'localhost:3000/api/notify/db/attached_datawarehouse' x-metabase-apikey:apikey -pb
{
    "success": true
}
```

It will sync existing tables
```shell
❯ http post 'localhost:3000/api/notify/db/attached_datawarehouse' table_name=existing schema_name=public x-metabase-apikey:apikey -pb
{
    "success": true
}
```

it will error if it cannot find a table
```shell
❯ http post 'localhost:3000/api/notify/db/attached_datawarehouse' table_name=new schema_name=public x-metabase-apikey:apikey -pb
{
    "cause": "Unable to identify table 'public.new'",
    "data": {
        "schema_name": "public",
        "status-code": 404,
        "table_name": "new"
    },
    "message": "Unable to identify table 'public.new'",
    "schema_name": "public",
    "table_name": "new",
    "trace": [],
    "via": [
        {
            "data": {
                "schema_name": "public",
                "status-code": 404,
                "table_name": "new"
            },
            "message": "Unable to identify table 'public.new'",
            "type": "clojure.lang.ExceptionInfo"
        }
    ]
}
```

if i create that table
```sql
attached=# create table new (id int);
CREATE TABLE
```

it will then find and sync it

```shell
❯ http post 'localhost:3000/api/notify/db/attached_datawarehouse' table_name=new schema_name=public x-metabase-apikey:apikey -pb
{
    "success": true
}
```

* formatting

* Tests for attached datawarehouse

* PR nits

typo in `thorw` -> `throw`
comment explaining why `find-and-sync-new-table` is always sync
gensym the db name in test
remove a binding for a fn `sync!` that's only called once
test `{:sync_db true}` syncs the whole db

* stupid formatting 



* Use absence of table_name as indicator to sync database
