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.

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.
