[omurilo]

Add a Oracle Cloud Infrastructure as provider to deployment terraguard

[Rapha-Borges]

I've created a pull request on your branch with some minor fixes. The details are as follows:

The declaration of the variable availability_domain with the number type enables the project to be used in accounts with limited resource availability. Free accounts have resource limitations based on availability domains (AD).

• README.md
  [X] Modified the oci session authenticate command to use sudo in accordance with project requirements.
  [X] Added TF_VAR for region and availability domains, making it easier to apply in other regions.
  [X] Added instructions to run the sudo terraform -E command for the use of previously exported TF_VAR.

• modules/.../variables.tf
  [X] Refactored for use with modules

• variables.tf
  [X] Added the variable availability_domain and removed the default field in the region variable.
  [X] Refactored for use with modules

• modules/instance/main.tf
  [X] Implementation of the availability_domain variable.

• .gitignore
  [X] Added **/.terraform* to the .gitignore file.

Fixed!

Once you make the proposed changes, I believe it will be ready for the merge.

I successfully tested it on three different accounts.

Ok! @P0ssuidao if the variable formats work for you, I believe you can proceed with the merge. Everything works fine, and looks great!
