Remove usage of `PromiseOrVoid`, it makes it difficult to consume
the API via `await`. For each async method, define multiple variants
to correctly describe what's returned when a callback arg was provided
(`void`) and what's returned when called with no callback
(`Promise<T>`).

When writing tests, for performance reasons we often want to reuse
the same data-source instance for many tests suites. At the same time,
we want to keep such test suites independent and allow them to reuse
the same model name for different model classes.
Juggler does support redefinition of a model with the same name.
This change is adding a new API called that allows tests to remove all
old models before creating new ones. This API would be typically
called from a `before` hook.

add beginTransaction method which calls begin
method from the Transaction class which in turn
calls the connector's beginTransaction method if
it supports transactions.

Define two new types: ModelSettings and ModelProperties to describe the
objects describing model properties and settings.
Add static property `base` and static method `extend` to the definition
of `ModelBase` class.
Add property `defaultModelBaseClass` to `ModelBuilder` class definition.
Fix `PropertyDefinition` interface: remove `name`, add optional `id`.
Callback's first argument is an optional Error now. Was: required `any`.
PersistedModel methods return `PersistedModel` now. Before this change,
methods were returning `PersistedData` (`PersistedModel | AnyObject`).
The problem with `AnyObject` is that it does not contain any
`PersistedModel` instance data and cannot be assigned to functions
expecting `Partial<PersistedModel>`. As a result, consumers of this API
were forced to either cast the result to `PersistedModel` (which feels
wrong) or deal with the `AnyObject` case (which never happen at
runtime).
Fix definition of `ModelData<T>` to `T | Partial<T>`. Before this
change, `ModelData` allowed any values not related to the actual
model at all, for example arrays.
Use case:
1. Configure a datasource with lazyConnect = true
2. Do NOT start the DB
3. Start the app
4. Send first request and it fails to connnect to the DB
5. Start the DB
5. Requests are now served correctly
