**What**
Align the index engine API to be similar to the Query API
## Example
```ts
// Benefit from the same level of typing like the remote query
const { data, metadata } = await indexEngine.query<'product'>({
fields: [
"product.*",
"product.variants.*",
"product.variants.prices.*",
],
filters: {
product: {
variants: {
prices: {
amount: { $gt: 50 },
},
},
},
},
pagination: {
order: {
product: {
variants: {
prices: {
amount: "DESC",
},
},
},
},
},
})
```
CLOSES: FRMW-2704
**What**
Re-structure the Query graph API as well as introduce dynamic typing from schemas on the filters and better handling of relation treatment for fields/filters inference

what:
- adds variant inventory link management endpoints:
```
Link inventory item to variant
POST /products/:id/variants/:vid/inventory-items
Update variant's inventory item link
POST /products/:id/variants/:vid/inventory-items/:iid
Unlink variant's inventory item
DELETE /products/:id/variants/:vid/inventory-items/:iid
```
- a batch endpoint that does the above 3 across variants
```
POST /products/:id/variants/inventory-items
```
**What**
- automatically build and consume connection and container loader if not exported by the module
- therefore load the services and repositories automatically, including baseRepository
- automatically build run and revert migrations if not provided
- cleaup modules to remove extra unnecessary bits and pieces
- remove the `initializeFactory` in favor of using `medusaApp`
Should drastically improve the module building DX by removing a lot of boilerplate to handle by the user, that plus the base entity should simplify quite a lot the flow cc @shahednasser
**Note**
I had to choose a way to identify connection and container loader from the exported loader from the module. I decided to go with named function `connectionLoader` and `containerLoader`, also, now the factories will return named function so if the user use the factories we are providing to build those loaders, the function will also be named and identified
