[CLI Improvements] Migrate Tests to resource manager architecture - Documentation

[danielbdias]

Tests are the core of the application and can be found everywhere in both documentation and examples. For this task the idea is to go through the files which are exposed or used by the community and update them with the changes done as part of the test resource migration.

Acceptance Criteria

AC1
As a user looking a the documentation website
Every part of the site which includes test information
Should match the changes done as part of the migration to resources

AC2
As a user looking at the public readmes from examples or anywhere in the repo
I should be able to see the updated version after the test resources migration
And all of the examples should work as expected

@schoren this should be done too right?

the docs has been updated with the new run command, but I'd like to make sure the doc is good enough to understand how to manage tests and transactions. Input from @adnanrahic would be great
