Lucas Roesler 0fef825fb4 Add support to specify secrets in services
**What**
- During function creation, accept an array of strings defining swarm secrets
that are required for the service
- Update docs
- Add new guide on using the secrets capability
- Add new sample function to highlight using environment variables
- Update `ApiKeyProtected` sample function to utilize the new secrets
capabilities

**Why**
- This allows secrets to remain encrypted at rest instead of being unencrypted
in environment variables and yaml files.

Fixes #285

### Api-Key-Protected sample
To use this sample provide a secret for the container/service in `secret_api_key` using [Docker Swarm Secret](https://docs.docker.com/engine/swarm/secrets/#defining-and-using-secrets-in-compose-files).
Then when calling via the gateway pass the additional header "X-Api-Key", if it matches the `secret_api_key` value then the function will give access, otherwise access denied.
