Remove remaining portions of rest api authentication code

Problem

API Security used to use authentication on it's rest apis. This was disabled, but much of the code was left in while the architecture stabilized. Now that it's stable, the remaining code can be removed.

Proposal

1. Identify location of authentication code
   1. Generating new api key on first start
   2. Commented out code in startup.cs
2. Remove code
3. Update tests as needed
