Remove 'start_time' in 'InspectionMetadata'

[tsundvoll]

Describe the improvement you would like to see
Remove the 'start_time' attribute from the 'InspectionMetadata' class in 'src/robot_interface/models/inspection/inspection.py'. Time is anyways baked into the 'time_indexed_pose' attribute. Remember to update everywhere the class is used, also in the different robot repositories.

How will this change existing functionality?
I can't see that start time is used anywhere now, so it will not break any existing functionality.

Would it make more sense to change TimeIndexedPose to Pose and keep "start_time"?
