ci: Add tft plan and workflow

This change is for running tests in Testing Farm CI. This is a replacement for BaseOS CI that we are currently using. Running it Testing Farm gives us more control. It adds a workflow for running tests, and a plans directory containing a test plan and a README-plans.md with some info. Note that this workflow runs from the main branch. This means that changes to the workflow must be merged to main, then pull requests will be able to run it. This is because the workflow uses on: issue_comment context, this is a security measure recommended by GitHub. It saves us from leaking organization secrets. The functionality is WIP, so await future fixes and updates. Signed-off-by: Sergei Petrosian <[email protected]>

+# Introduction CI Testing Plans
+
+Linux System Roles CI runs [tmt](https://tmt.readthedocs.io/en/stable/index.html) test plans in [Testing farm](https://docs.testing-farm.io/Testing%20Farm/0.1/index.html) with the [tmt.yml](https://github.com/linux-system-roles/timesync/blob/main/.github/workflows/tmt.yml) GitHub workflow.
+
+The plans/general.fmf plan is a test plan that is general for all roles. It does the following steps:
+
+1. Provisions two machines, one used as an Ansible control node, and second used as a managed node.
+2. Does the required preparation on machines.
+3. For the given role and the given PR, runs the general test from [test.sh](https://github.com/linux-system-roles/tft-tests/blob/main/tests/general/test.sh).
+
+The [tmt.yml](https://github.com/linux-system-roles/timesync/blob/main/.github/workflows/tmt.yml) workflow runs the above plan and uploads the results to our Fedora storage for public access.
+This workflow uses Testing Farm's Github Action [Schedule tests on Testing Farm](https://github.com/marketplace/actions/schedule-tests-on-testing-farm).
+
+## Running Tests
+
+You can run tests locally with the `tmt try` cli.
+
+### Prerequisites
+
+* Install `tmt` as described in [Installation](https://tmt.readthedocs.io/en/stable/stories/install.html).
+
+### Running Tests Locally
+
+For now, this functionality requires you to push changes to a PR because the plan only runs from the main branch, or from the PR branch.
+So this is WIP.
+
+To run tests locally, in the role repository, enter `tmt run plans --name plans/general <platform>`.
+Where `<platform>` is the name of the platform you want to run tests against.
+
+For example, `tmt run plans --name plans/general Fedora-40`.
+
+This command identifies the plans/general plan and provisions two machines, one used as an Ansible control node, and second used as a managed node.
+
+You can also use `tmt try` to get to an interreactive prompt and be able to ssh into test machines.
+You must run `tmt try -p plans/general Fedora-40`, and the in the promt type `p` to prepare the machines, then `t` to run the tests.
