OTP override for development only

## Description

If the environment variable `INFECTION_MONKEY_OTP_OVERRIDE` exists, we want to skip enforcement of OTP/Authentication for the `Agent` role. This will keep development (running from source) simpler and easier for developers.

Ideally, this override feature would not even be included in release binaries.

## Tasks
- [ ] Define an environment variable with a reusable "OTP"
- [ ] If the environment variable exists **on island startup**
- [ ] Force the user to confirm [y/n] that they still want to start the Island
- [ ] Pass the "override OTP" to the OTP endpoint/service
- [ ] Implement logic in the OTP endpoint/service to accept the override OTP
- [ ] Log a warning every time we accept the override OTP
- [ ] Log a warning when this component is constructed
- [ ] Try to find a way (similar to `#IFNDEF`) to exclude OTP override from release binaries
