toaster: add tox.ini file to execute test suite

Updated tox file to fix enviroments variables.
to run tox use the following command:
tox -e env_name -c /path/to/file/tox.ini
See tox cli https://tox.wiki/en/latest/cli_interface.html
The variable env_name is linked to the python versions (py38, py39, py310).
If env_name option is not set,  the test suite will run for all indicated versions.

It was also modified the webdriver options for chrome to run selenium test in console because of the error detected in the previous test run
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: Chrome failed to start: exited normally.
  (session not created: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
