[QA] Run automated GUI tests in Windows

[Talank]

Describe the QA issue

Currently we are running all the automated tests in ubuntu, but with some changes, we should be able to run the tests in Windows as well (at least run it locally).

Steps to reproduce the issue

1. Download ownCloud client (already built) and install it in windows.
2. Set up ownCloud core (if you are using virtual machine, then you can use the core that you have set up in your host, you might need to configure the host file of the virtual machine and trusted_domains domains on core config)
3. Download squish for windows (for example squish-6.7.2-qt512x-win64-msvc141.exe) and install it
4. Install python 3.8 on windows
5. Download PythonChanger.py script and save it inside your squish installation directory
6. run python PythonChanger.py from squish installation directory
7. Run owncloud-test-middleware (just like core, you can run it in host machine, if you are using virtual machine for windows. Alternatively, you can run middleware in drone). You might need node installed if you want to run middleware locally.
8. Install required python libraries
   • pip install requests
   • pip install pycairo
   • pip install PyGObject

NOTE the PyGObject library is not available in windows. You can install this library using mingw as shown here. However, the problem so far is that this tool can not be used to install python 3.8 so far. And we need python 3.8 for squish.

Tests skipped for Windows:

• Sharing link with expiration date (difference in date format)
• Syncing a folder having space at the end (white space is trimmed)
• Filenames that are rejected by the server are reported (invalid file name for windows)
• Sync long nested folder (windows doesn't allow long path name)
• Invalid system names are synced in linux (linux only)

Feature disabled for Windows:

• Screenshots
• Stacktracing

It is blocked, until we can figure out a method to install python 3.8 and pgGObject library in python 3.8 in windows

Now we can run Squish tests in Windows.
