requirements.txt doesn't have fixed versions

Hi,

I tried running a fresh installation of the fogify framework, but ran into issues with certain python packages no longer being supported. For instance I after running

sudo docker-compose build
sudo docker-compose -p fogemulator up

I would see the following error messages

controller_1  | Traceback (most recent call last):

To fix this I added strict versioning to the requirements.txt file so it would look like

Flask==1.1.2
Werkzeug==1.0.1
Flask-API==2.0
requests==2.25.1
docker==5.0.0
Flask-SQLAlchemy==2.5.1
pyyaml==5.4.1
python-dateutil==2.8.1
psutil==5.8.0
py-cpuinfo==8.0.0
netifaces==0.11.0
nsenter==0.2
uWSGI==2.0.19.1

Let me know if you have any questions.
