psutil 5.7.0 issue on Windows 10

[stennie]

There is apparently an issue with psutil 5.7.0 on Windows 10 that causes mlaunch list to fail with a permission error: giampaolo/psutil#1723

For example:

mlaunch list
Traceback (most recent call last):
  File "c:\program files (x86)\python38-32\lib\site-packages\psutil\_common.py", line 449, in wrapper
    ret = self._cache[fun]
AttributeError: _cache
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
  File "c:\program files (x86)\python38-32\lib\site-packages\psutil\_pswindows.py", line 679, in wrapper
    return fun(self, *args, **kwargs)
  File "c:\program files (x86)\python38-32\lib\site-packages\psutil\_common.py", line 452, in wrapper
    return fun(self)
  File "c:\program files (x86)\python38-32\lib\site-packages\psutil\_pswindows.py", line 766, in exe
    exe = cext.proc_exe(self.pid)
PermissionError: [WinError 24] The program issued a command but the command length is incorrect: '(originated from NtQuerySystemInformation)'

Installing the previous minor version (python3 -m pip install psutil==5.6.7) resolves the issue.

mtools' psutil dependency should specify <5.7.0 until this is resolved.
