Current behavior (how does the issue manifest): When running a Flogo exe on a windows command prompt the $env.VARNAME assignment does not work for EnvVars that have been set via the windows SET command. This is the same for both a CMD prompt and a BAT script

System level EnvVars work. But the following syntax doesn't.

set MYVAR="Hello" flogotest.exe

Will not be able to pickup MYVAR

Expected behavior: Should be able to get EnvVars regardless of how they are set. Windows Powershell works

Minimal steps to reproduce the problem (not required if feature enhancement): Create a flogo app that pulls in a env var .....

What is the motivation / use case for changing the behavior? Lack of consistency across platforms

Please tell us about your environment (Operating system, docker version, browser & web ui version, etc): Windows 10
