During container startup we end up spending a fair amount of time
encoding/decoding json.
This cuts out some of that since we already have the decoded object in
memory.
The old flow looked like:
1. Start container request
2. Create file
3. Encode container spec to json
4. Write to file
5. Close file
6. Open file
7. Read file
8. Decode container spec
9. Close file
10. Send to containerd.
The new flow cuts out steps 6-9 completely, and with it a lot of time
spent in reflect and file IO.

Instead of a timeout the context is cancelled on error to ensure
proper cleanup of the associated fifos' goroutines.
