Consider adjusting collection data sources default name

[austinvalle]

Background

After #78 added support for collection data sources (by automatically creating a root SetNested or Set attribute), we decided to automatically set the name of the attribute to be the same as the data source name.

This may not be desired if the data source name has multiple words like aws_secretsmanager_secrets.

Possible solutions

• Adjust the attribute name to split on underscore and take the last word
• Add a configuration option to the generator config to allow a custom name:

Example

data_sources:
  petmanager_pets:
    read:
      path: /pet/findByStatus
      method: GET
    schema:
      collection_name: pets
