Schedule missions for the robot automatically

[aeshub]

Describe the new feature you would like to see
Operators have requested the functionality to schedule missions automatically without them needing to be in the loop and press start for different missions.

Describe the solution you'd like
It should still be possible to schedule missions the way we do today. Additional functionalities should be

• Schedule a mission that runs with a certain interval. Whenever the interval hits the mission should be scheduled to the relevant robot.
• Schedule a mission to run once at a certain time in the future (for example at 1645 to monitor a specific event that happens irregularly)

These two can be a good start and then something to build upon in the future.

How will this feature affect the current Threat Model?
A consideration to keep in mind is how is this handled by the battery of different robots. Will they charge and then perform missions?

The limits for this feature should be defined before we start on it (can queue the next two months for example)
