This is the second part of the bor milestone release it contains the
following changes:
* Initialize services
* This is a change from the initial pull request I have moved all of the
initialization to the bor engine. To facilitate this I have just passed
in the heimdall client interface, rather than the whole engine
* Stage processing
* This is also a change from the original PR - the code is contained in
the bor heimdall stage rather than in headers - the effect should be the
same, but this needs testing
