issue when using multipe aws components where one doesn't have endpoints

[bluedread]

Is your proposal related to a problem?

We had a config with multiple AWS site components. One of those doesn't use endpoints:

sites:
  - identifier: tst-aap
    endpoints:
      internal:
        url: some.url
        ...
      external:
        url: another.url
        aws:
          ...
  - identifier: tst-noot
    aws:
      ...

There were componentes deployed to the tst-aap site that used endpoints, and components to tst-noot that didn't use endpoints. When deploying with mach composer version 2.2 this worked.

When switching to 2.8 this generated an error:

| Error: An error occured:
|
| failed to render resources: plugin aws failed to render resources: aws component requires undeclared endpoint: internal

Describe the solution you'd like

It should be possible to deploy components that don't require an endpoint to a site that doesn't use those, while keeping different aws sites in the same configuration yaml file.

Describe alternatives you've considered

We've split up the configuration into multiple files, this unblocked us.
