OpenStack director introspection reports 384MB of RAM instead of 384GB

Issue

• During introspection on an HP DL360p, it mistakenly reports the amount of ram in MB instead of GB. This leads to problems of "no valid host found" as it can't find nodes with proper amount of RAM.

• Here's the output after introspection, note u'memory_mb, the correct value should be 384GB (393216):
