As a user, I want to create a key/value pair via Astral

[suprjinx]

Given a valid JWT token

When a POST request is sent to /astral/v1/secrets (path TBD)

Then
Create a vault policy for newly created key/value pairs and assign it to the originating user/vault entity such that if they go to vault directly they will have access to the created object.

And
retrun a 201 Created response to the caller

Success criteria: the object created in Astral is available directly in vault

If the JWT is invalid (standard error handling)

If any error response is received from Vault, log the error response from Vault with the request_id to the operational log and pass an error response to the caller with the request id.
