Is your feature request related to a specific problem?

For the first version of the data map UI, there must be a way to draw connections between systems which depend on each other and use data from each other, so that data map consumers can see how various systems are related on the visual map.

Describe the solution you'd like

The fideslang system model contains a field called system_dependencies which should be used to save the relationships between systems described above. In the UI, create a picklist input which allows the user to select from all currently registered systems, and save this reference in the system declaration.

Describe alternatives you've considered, if any

This is a short - medium term solution which will be expanded upon as we continue to work on describing data movement between systems in an environment.
