(PE-17359) Adding Windows frictionless agent support (#28)

This commit adds support for windows frictionless agent.
There was a change to the pe_repo logic, to make sure the master
downloads the new windows script.
Also there is the addition of a powershell script, which is the
direct equivlant of curl | bash.
