esx: Make the conf parser compare names case insensitive in VMX mode

The keys of entries in a VMX file are case insensitive. Both scsi0:1.fileName
and scsi0:1.filename are valid. Therefore, make the conf parser compare names
case insensitive in VMX mode to accept every capitalization variation.

Also add test cases for this.
