## Summary
* Adds conflict versioning by exposing the "_version" from the saved object system. It renames "version" to "_version" so that we can use regular "version" later for versioning things for pre-packaged lists abilities.
* Utilizes `t.OutputOf` in the requests and the data types to give us more correctly types
* Removes the `Identity` utility as that is adding confusion and can confuse vs code rather than improves things
* Removes extra types that were causing confusion which was an idiom from io-ts
* Changes the wording of `Partial` by removing that and instead focuses the request types on either client side or server side at this point.
NOTE: The UI can migrate to holding onto the `_version` and then push it back down when it wants to migrate to using the conflict resolution. If the UI does not push it down, then a value of undefined will be used which is indicating that no conflict errors are wanted.

Example of the error you get if you do an update of an exception list and someone else has changed it:
```ts
{
"message": "[exception-list:a08795b0-c85f-11ea-b1a6-c155df988a92]: version conflict, required seqNo [1074], primary term [1]. current document has seqNo [1077] and primary term [1]: [version_conflict_engine_exception] [exception-list:a08795b0-c85f-11ea-b1a6-c155df988a92]: version conflict, required seqNo [1074], primary term [1]. current document has seqNo [1077] and primary term [1], with { index_uuid=\"a2mgXBO6Tl2ULDq-MTs1Tw\" & shard=\"0\" & index=\".kibana-hassanabad_1\" }",
"status_code": 409
}
```
Lists are the same way and flavor, they encode the _version the same way that saved objects do. To see those work you run these scripts:
```ts
./post_list.sh
./post_list_item.sh
./find_list.sh
./find_list_item.sh
```
