Clarify Gemfile to default to running on Fog release

Our default position is to run against the version of
fog in vcloud-tools.gemspec. It should be rare that regular
users will need to run against an unreleased version.

Removing the comments that demonstrate how to do this,
in favour of preserving in this commit.
Give user the valid choices for fence_mode
Clean up some line length readability issues
Move helper methods into a local scope

Rspec, when run with multiple files, seems to run them in the same namespace/scope.

This means that any local helper methods can potentially override one another.

Move all helper methods into the top level describe..end scope to effectively
localise them.
Move orgVdcNetwork integ test so does not auto-run

The integration test for org_vdc_network takes 7+ minutes. Moving it
so that it does not run as part of the 'rake integration_test' run,
until we figure out how to speed it up.
