Extract spec config to spec_helper and support files

[fbuys]

Description

• I added a spec_helper file.
• Moved config into the spec_helper file.
• Added support files and moved helper functions to support files.
• Turn spec profiling off for simpler spec output.

Motivation and Context

Part of the solution for: #206

• We would like to split the specs into smaller spec files.
• I believe the first step is to take all the config and helper files out of the current spec file.
• With a simpler spec file it will be easier to extract feature and unit tests.

Much inspiration taken from here: https://lokalise.com/blog/how-to-create-a-ruby-gem-testing-suite/

How Has This Been Tested?

Automated testing.
This is a refactor so all existing specs still pass.
