prep-source-repos/rack-testing

Here we find:

* sample nodes.json and networks.json files

* an example devtestrc which we use when testing in one of the HP test racks

To use:

* follow the main readme to get your source repos downloaded and variables
  defined.

* create appropriate customised nodes and network json files

* run it::

    devtest.sh  --trash-my-machine --nodes $PATH_TO/nodes.json --bm-networks $PATH_TO/bm-network.json
