slight changes to the plenary machine template
slight changes to the plenary machine template

Added rack location into the template for the esp folk,
chassis information (this will be used to drive the node mapping
file for jasona, and mconsole configuration maybe), and slight
cleanup to the console configuration to make it simpler and more
in line with the QWG style of things. This is all dependent
on the "racks" domain of templates, which must be put into prod
before using this code (the racks template domain is backwards
compatible with existing usage, so I'll do that well in advance)
