one command contains:
- command
- status
- command_id
- tstamp
command may contain one out of following strings:

status may contain one out of following strings:

command_id is a random generated 4 chars long integer to identify the exact command between Server frontend Database and ESP
tstamp is the exact Date at the first ever creation of the db entry and does not say anything about completion or rejection.
NOTE:
A created command is marked as failed after 5 minutes if its status is still pending, to ensure that no processes continue after a communication failure in the chain.
