feat: Add index method for EDV client and BDD test

[DRK3]

• Added a method to the EDV client for asking an EDV server to add indexes.

• Added a BDD test step for adding an index using the client.

• Added log message to server when receiving a request to add indexes.

• Changed "attribute key" to "attribute name" to keep in line with current draft PR in EDV spec for the "add index" endpoint.
