Adds minimal implementation to deploy a Salt minion on Windows including support for pre-seeding the keys
redirect output of mkdir statement to out-null in bootstrap-salt.ps1
sometimes salt-minion wouldn't start - this seems stable so far across 10 deploys
Retries starting the salt-minion service several times and adds elevated: true to salt calls
Remove Salt Master & Salt Syndic changes - not supported on Windows by Salt
Also copy minion config in bootstrap-salt.ps1 & update Salt docs to mention syndic/master not supported on Windows
minor indentation fix
Only try to copy keys & config if they have been uploaded
Wait for  to be populated & explicitly check for Running status of service
Now wait for service to be registered before trying to start it
