.SYNOPSIS
Imports a cert from WACS renewal into SQL Server
.DESCRIPTION
Note that this script is intended to be run via the install script plugin from win-acme via the batch script wrapper. As such, we use positional parameters to avoid issues with using a dash in the cmd line. 

Proper information should be available here

https://github.com/win-acme/win-acme

.PARAMETER NewCertThumbprint
The exact thumbprint of the cert to be imported.


.EXAMPLE 

ImportSQL.ps1 <certThumbprint>

./wacs.exe --target manual --host hostname.example.com --installation script --script ".\Scripts\ImportSQL.ps1" --scriptparameters "'{CertThumbprint}'" --certificatestore My --acl-read "NT Service\MSSQLSERVER"
