Launch POST response is not sent if disk is full

[Lari-Matias Orjala]

When the disk is full but the service is responsive, service-api fails to process a launch POST request and send a response to the client application.

The function should timeout or fail and then send a response even if it cannot process the request so the client won't wait indefinitely. This mostly affects smaller-scale or development deployments without proper disk management.

Steps to reproduce:

1. Start the service.
2. Fill the disk to full.
3. Send /api/v2/<project>/launch POST request.
