(MAINT) Drop MockVsphereHelper (#10)

* (MAINT) Update specs to remove VsphereHelper

VsphereHelper is no longer relevant since vmpooler doesn't use vSphere/vCloud any more.

* (MAINT) Drop conflicting, unused dependency on beaker-abs

* (MAINT) Conditionally pin fakefs '< 0.14.0' for Ruby < '2.3.0'

* (MAINT) Remove more VsphereHelper references

And minor whitespace cleanup

* (MAINT) Drop unused beaker-abs dependency

Could have sworn I fixed that... maybe in a different branch?
