Amplify Console's API/Data Sources Page does not load all items

**Is your feature request related to a problem? Please describe.**
The data sources section of the amplify console currently lists the tables present in am environment, along with pagination for the same. However, it only seems to load the first page worth of items.

As a separate issue, the amplify console also shows the `LambdaDataSource` which is, well, a lambda. It should probably filter these based on the data source type being DDB, or at least link them to a lambda if they are of the lambda type.

**Describe the solution you'd like**
Paginator to work to show all resources :-)

**Additional context**
For example, I have a list of data sources in the amplify console that looks like this:

Whereas the actual list of tables (filtered on the env name) looks like this:

* table names hidden because they're not terribly relevant to the example, just know there's a lot of them.

Start at Amplify Console's API/Data Sources page and reproduce the listing with an environment containing more items than one page. Trace the paginator and data-source display; done means all resources are reachable through pagination and LambdaDataSource entries are filtered or linked as described.
