Terraform Support for Managing Reserved IP Addresses

[AniJ98]

📝 Description

This PR introduces comprehensive functionality and tests for Reserved IP Addresses in the terraform provider. The changes are necessary to provide robust support for managing Reserved IP addresses through terraform. The changes include:

Implementation of core Reserved IP operations:

• Listing Reserved IPs
• Getting a specific Reserved IP
• Reserving a new IP
• Deleting a Reserved IP

Test coverage:

• Resource test - Covers testing the functionality of reserving and deleting a reserved IP Address
• Datasource test - Covers testing the functionality of listing all reserved IP addresses and fetching a particular reserved IP Address.

✔️ How to Test

What are the steps to reproduce the issue or verify the changes?

1. Ensure you have a valid Linode API token.
Set up your environment:


   export LINODE_TOKEN="your_token_here"


2. To run only Reserved IP related tests:


   make int-test PKG_NAME="linode/networkreservedips"

To run a specific test:

  make int-test PKG_NAME="linode/networkreservedips" ARGS="-run TestAccDataSource_reservedIP"

3. Verify the test output for any failures or unexpected behavior.

Note:

Ensure you have proper permissions and sufficient quota in your Linode account to perform Reserved IP operations. Some tests may create and delete resources, so use a testing environment if possible. This test expects the account to have 0 prior reservations.
