Remove the directory importer script 🔥 (PP-213)

[jonathangreen]

Description

Remove the directory importer script, since we are not using it anywhere, and have decided to host content like this elsewhere in the future.

Motivation and Context

Our database migration for #1189 failed on the Columbia staging server because it had an external integration configured with “Manual intervention“ as the protocol. This collection was added via the directory_import script. This script appears to create collections that cause problems with the new integration settings system.

Instead of fixing this issue, we've decided to remove the script.

How Has This Been Tested?

Running tests.

Checklist

• I have updated the documentation accordingly.
• All new and existing tests passed.
