Rails Template for starting new Ruby on Rails project

[coolprobn]

We already have the work with Rails template ongoing in another repo, we need to cleanup and add required packages that we use in Truemark whenever starting new Rails project.

For start, we should include app that is setup with gems that we use in all our Rails apps like:

• Devise for authentication
• Pundit for authorization
• RSpec for writing tests (I am leaning towards Minitest more nowadays because it is pure Ruby)
• Rubocop for best practices
• Overcommit for git hooks
• Gitlab CI for CI since we host most of our apps in Gitlab
• etc...
