Provide a set of utility scripts that populates developer data via the REST API

**Is your feature request related to a problem? Please describe.**
For various use cases like:
- Visits
- Alarms

it would be terribly handy to have a set of sample data that would make the system behave like there has been activity.

We can populate this via the Command Centre interfaces but it would be handy to automate this.

Post population of the database we could snapshot the database and restore it to state which would save repopulating this data.

**Describe the solution you'd like**
Write and make available a set of scripts that builds on top of the REST client to populate a logically set of data, ideally that builds on top of the data that the Command Centre comes with.

- Query what is already part of the Command Centre
- Use references from that to populate the events

**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features you've considered.

**Additional context**
- Allow this to be run as a `task`
- Make this a deliberate task that the user has to run
