Write and host Microservice to have a GetEchoMap service

[tsundvoll]

Describe the new feature you would like to see
A server that exposes an API to get 2D maps from ECHO

Describe the solution you'd like
Parameters (roughtly):

• Plant name
• Area name
• x_min, x_max
• y_min, y_max
• z_height

Outputs 2D map with this crop.

We could then call this API for every new mission. To find the x- and y- -min and -max, we could iterate over all the tasks in the mission.

Points to solve:

• Caching of images (either on Flotilla side or on the API side)
• Access control to the images (and the sources for generating the images, the 3D models)

We probably want to host this in Radix.

Consider having the source code for the microservice in the Flotilla repository still.

How will this feature affect the current Threat Model?
Easier to have this as a separate module for other users.
