(maint) Remove stale vagrant support

Support to run the acceptance tests on local Vagrant instances had grown

Vagrant.
(maint) Coppy in the node configurations and pre-suite for pe test runs

The PE acceptance tests use their own set of configurations and a
pre-suite install step.  These were moved in from the tmpfosstestsforpe
repository.
