Matt Davis ba353b0f8f fix ambiguous cert selection in WinRM enable script ()
Rather than trying to guess which cert we just generated,   parse the generated cert data and extract the thumbprint directly.

#Requires -Version 3.0
# Configure a Windows host for remote management with Ansible
# -----------------------------------------------------------
#
# This script checks the current WinRM (PS Remoting) configuration and makes
# the # necessary changes to allow Ansible to connect, authenticate and
# execute PowerShell commands.
#
# All events are logged to the Windows EventLog, useful for unattended runs.
#
# Use option -Verbose in order to see the verbose output messages.
#
# Use option -CertValidityDays to specify how long this certificate is valid
# starting from today. So you would specify -CertValidityDays 3650 to get
# a 10-year valid certificate.
#
# Use option -ForceNewSSLCert if the system has been SysPreped and a new
# SSL Certifcate must be forced on the WinRM Listener when re-running this
# script. This is necessary when a new SID and CN name is created.
#
# Use option -SkipNetworkProfileCheck to skip the network profile check.
# Without specifying this the script will only run if the device's interfaces
# are in DOMAIN or PRIVATE zones. Provide this switch if you want to enable
# WinRM on a device with an interface in PUBLIC zone.
#
# Use option -SubjectName to specify the CN name of the certificate. This
# defaults to the system's hostname and generally should not be specified.
