IF ClientManager GETS KILL OR HUP COMMAND:
	-> Send latest "sendStatus" before going down

1. Check if all Perl modules are installed
2. download and install all needed perl modules
3. GET https://tech.onetipp.net/task.php
4. do: ForceInternalDockerImageAPTUpdate
5. do: ForceDeepLearningTrainingSoftwareUpdate
6. do: ForceClientManagerUpdate
	
	6.1: if ForceClientManagerUpdate == 1: ELSE GOTO "STEP 7"
	6.2: Calculate MD5 Hash of ClientManager.pl
	6.3: if CalcLocalMD5(ClientManager.pl) NOT EQUAL ForceClientManagerUpdate->XML(ClientManager.pl->md5())
		6.4. Download new ClientManager.pl
		6.5. Unpack PBZIP2 new ClientManager.pl
		6.6. RESTART: ClientManager.pl

7. Create Paths:
	7.1. /var/tmp/onetipp
	7.2. /var/tmp/onetipp/chainer/
	7.3. Copy ForceDeepLearningTrainingSoftwareUpdate to /var/tmp/onetipp/chainer/
	7.4. Create /var/tmp/onetipp/chainer/data/
	7.5. Create /var/tmp/onetipp/chainer/cv/
	7.5. Create /var/tmp/onetipp/chainer/cv/{$HASHID}/
	7.6. Create /var/tmp/onetipp/chainer/data/{$HASHID}/input.txt
	7.7. Start train.py --folder=data/{$HASHID}.txt --cv=cv/{$HASHID}
		7.7.1: Keep Process ID of train.py
		7.7.2: Keep {XML}->{$HASHID}
		7.7.3: Keep Process_STARTTIME in unixtimestamp
		7.7.4: Keep {XML}->{LANGUAGE}
		7.7.5: Keep {XML}->{worktime}
		7.7.6: Sleep: 60 Seconds
		
8. Wake up from 60 Seconds sleep
8.1: Check if python "train.py" PID is still running
8.2: Check if (Process_STARTTIME*{XML}->{worktime}) >= current_unixtimestamp()
	8.2.1: if (Process_STARTTIME*10minuten) >= current_unixtimestamp() -> Send "sendStatus"
	8.2.2: if no: sleep another 60 seconds
	8.2.3: if yes: -> Send "sendStatus" && kill "train.py"
	8.2.3.1: "START AGAIN AT DO STEP 3": GET https://tech.onetipp.net/task.php
