Too old version of paramiko in requirements.txt

[212850a]

It's too old version of paramiko (version 2.7.1) is specified in requirements.txt when in reality it's not really much used.
As result when we try to install pyfos from pip today we have to stick to that old version and other packages which uses paramiko do not work correctly.

Is it possible to update required version of paramiko or change requirement to something like 'paramiko~= 2.7.1'?
