Port CVEX to Windows

[olegbck]

Windows is the second popular OS among our users:

It won't be possible to run CVEX straight on Windows, because Ansible doesn't support Windows, however Ansible can run on WSL. I made some research and this is so far I came up with. Dumping my notes:

+Install VirtualBox on Windows:
+https://download.virtualbox.org/virtualbox/7.0.22/VirtualBox-7.0.22-165102-Win.exe
+
+Install WSL on Windows:
+wsl --install
+Reboot Windows and then wait for Ubuntu installation. Open the Ubuntu WSL prompt and then perform the actions below.
+Install Vagrant on Windows:
+https://releases.hashicorp.com/vagrant/2.4.1/vagrant_2.4.1_windows_amd64.msi
+
+Install Vagrant in WSL:
+```
+wget https://releases.hashicorp.com/vagrant/2.4.1/vagrant-2.4.1-1.x86_64.rpm
+sudo apt install alien
+sudo alien -i vagrant-2.4.1-1.x86_64.rpm
+vagrant plugin install virtualbox_WSL2
+echo 'export VAGRANT_WSL_ENABLE_WINDOWS_ACCESS="1"' >> ~/.bashrc
+echo 'export PATH="$PATH:/mnt/c/Program Files/Oracle/VirtualBox"' >> ~/.bashrc
+source ~/.bashrc
+```
