Feature/cid 2776/create a webhook listener endpoint

[mohamedlajmileanix]

🛠 Changes made

A new endpoint to receive GitHub enterprise webhooks. First iteration, to process "push" events and send all other events as they are to the LeanIX backend (expected event types: "REPOSITORY", "PUSH", "ORGANIZATION", "INSTALLATION"). The processing of the push events, is limited to detecting change to the leanix manifest files within repositories and sending the change to the backend.

✨ Type of change
