* Adapted the powershell to connect to the central with a dedicated sql login
* reverted script 9_Update_FTPLogin_Central to the original version
* script 9_Update_FTPLogin_Central is executed on the central directly with a dedicated login
* reverted scripts 20_update_system_site_centrale.sql and 21_update_point_of_sale_centrale.sql to work locally only
* scripts scripts 20_update_system_site_centrale.sql and 21_update_point_of_sale_centrale.sql are executed on the cenrtal with a specific login and on the local instance
* when fetching the mac addresses, only take up interfaces in account and group the results by mac addresses, to avoid virtual mac addresses duplicate causing an error
