        Description

        Currently os::print_os_info outputs various interesting OS Information.
        The output is platforms dependent, on Linux currently the following information is printed :
        distro, uname, some important libversions, some limits, load average, memory info, info about /proc/sys, container and virtualization details and steal ticks.
        The OS uptime would be a helpful addition.

        This change adds a line of output giving the uptime in days, hours and minutes:
          "OS uptime <num> days <num>:<num> hours"

        This Information can be found in a hs_err file.
        Often, a recent reboot indicates that the undelying System has been changed (OS update etc). This might be the cause of the crash that produced the hs_err file.
