[Baesken, Matthias]

Hello, please review the following change .
It  enhances the hs_error file  output on Linux by  Cloud IAAS detection .

The DMI information  exposed  by the  /sys virtual filesystem  can be used to detect various Cloud IAAS on Linux.
It is helpful, for instance in support cases, to get some information about the Cloud IAAS in the hs_error file .
