[sdjmchattie]

User story As a Samples Extraction maintainer, I want to authenticate with a unique key when passing requests to Sequencescape.

Acceptance criteria To be considered successful the solution must allow:

• [ ] Update the config for the app to accept an API key for Sequencescape calls on the v2 API.
• [x] Ensure the deployment project sets this key on deployed versions.
• [ ] Update the app to always provide this key in the headers for v2 SS endpoints.
• [ ] Redeploy with an app specific API key for Sequencescape.
• [ ] Check that requests coming from the app into Sequencescape are using the API key.
• [ ] Remove the old / potentially compromised API key from Sequencescape's ApiApplication records.
