Add RSpec rails
Remove test directory in favor of spec

We're using RSpec instead of built in Rails tester.
Install RSpec in rails

Using Rails command
rails g rspec:install
Created empty Service controller and pending tests

- removed warnings from .rspec, seems to be a bug (as reported on SO)

Generated with Rails commands
rails g rspec:integration services
rails g controller Services
Ignore temporary vim files
Add Guard dependency
Default guard init rspec Gaurdfile
Implement initial index method for Services
Implemented getting all Services

ServiceController's index now returns all the Services in the database.

- wrote test to create a service and then retrieve it from the database.
- generated the model
- migrated the db

Generated with Rails command:
rails g model Service name:string group:string jira:string confluence:string
Create db seed for the CV service
