   CHECK SQL CONNECTION DETAILS
   CREATED BY: Vadim Melamed, EMAIL: vpasmodule@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO CHECK THE DATABASE CONNECTION DETAILS
.LINK
   https://vpasmodule.com/commands/Test-VPASSQLConnectionDetails
.PARAMETER NoSSL
   If the environment is not set up for SSL, API calls will be made via HTTP not HTTPS (Not Recommended!)
.EXAMPLE
   $CheckSQLConnectionDetails = Test-VPASSQLConnectionDetails -SQLServer {SQLSERVER VALUE} -SQLDatabase {SQLDATABASE VALUE} -SQLUsername {SQLUSERNAME VALUE} -AAM {AAM VALUE} -AppID {APPID VALUE} -Folder {FOLDER VALUE} -SafeID {SAFEID VALUE} -ObjectName {OBJECTNAME VALUE} -AIMServer {AIMSERVER VALUE}
.EXAMPLE
   $CheckSQLConnectionDetails = Test-VPASSQLConnectionDetails
.OUTPUTS
   $true if successful
   ---
   $false if failed
