[johlju]

Pull Request (PR) description

• SqlServerDsc.Common
  • Connect-SQL.
    • Add new parameter Encrypt.
• Connect-SqlDscDatabaseEngine
  • Add new parameter Encrypt.
• Invoke-SqlDscQuery
  • Add new parameter Encrypt.
  • Now shows the correct instance name when called using a server object (issue Invoke-SqlDscQuery: InstanceName always set to default value in should process messages #1918).
• SqlRS
  • Now uses the command Invoke-SqlDscQuery instead of Invoke-SqlCmd (issue SqlRs: Replace Invoke-SqlCmd with Invoke-SqlDscQuery #1917).
