* First pass using coercions

* Coercions

* Handle effective_type coercion_strategy in test data sets

* special-type -> semantic type in sample db

* Correct mismatch in validation preventing sync

* fixing up alternative date tests

* More passing tests

* Tests for values, nested queries, fetch metadata

* tests

* tests passing

* Fixup mongo qp for coercions

locally i have some failing tests that are off by 1 errors:

Fail in compile-time-interval-test

[36m:mongo[0m Make sure time-intervals work the way they're supposed to. [:time-interval $date -4 :month] should give us something like Oct 01 2020 - Feb 01 2021 if today is Feb 17 2021

* ee fixes

* UI to set coercion type

* Don't need to populate effective-type here

it actually has knock on effects:
- does more work now as almost every field has an update to do in
`add-extra-metadata`
- we have databases that have state that we don't create. druid for
example has stuff to mimic the dataset in tqpt/with-flattened-dbdef on
checkins but we don't actually create this. And our dbdef has a field
called "date" that is not present in the druid db, so if we attempt to
add metadata it fails and kills the rest of the metadata that we add.
- tests need this metadata to be present and the error causes field
visibilities (for example) to not be set

* Docstrings on shared lib

* Add effective and coercion to redshift expectations

* Fixup google analytics

* Derecordize instead of recordize the expectation

object details didn't work out well here. they added way more stuff
from the db than what is flowing through here.

```clojure

           {:name "DATE",

            :coercion_strategy nil,
            :semantic_type nil},
           :value {:type :date/all-options, :value "past5days"}}
    diff: - {:field
             {:description nil,
              :database_type "VARCHAR",

              :has_field_values nil,
              :settings nil,

              :fingerprint nil,

```

Object defaults adds quite a bit of stuff such that we'd be dissoc'ing
more than we are currently adding in
