docs: Document GitLab custom CI/CD variables
We introduced the QEMU_CI_AVOCADO_TESTING variable in commit f56bf4caf ("gitlab: Run Avocado tests manually (except mainstream CI)"), but forgot to document it properly. Do it now.

+Custom CI/CD variables
+======================
+
+QEMU CI pipelines can be tuned by setting some CI environment variables.
+
+Set variable globally in the user's CI namespace
+------------------------------------------------
+
+Variables can be set globally in the user's CI namespace setting.
+
+For further information about how to set these variables, please refer to::
+
+ https://docs.gitlab.com/ee/ci/variables/#add-a-cicd-variable-to-a-project
+
+Set variable manually when pushing a branch or tag to the user's repository
+---------------------------------------------------------------------------
+
+Variables can be set manually when pushing a branch or tag, using
+git-push command line arguments.
+
+Example setting the QEMU_CI_EXAMPLE_VAR variable:
+
+.. code::
+
+ git push -o ci.variable="QEMU_CI_EXAMPLE_VAR=value" myrepo mybranch
+
+For further information about how to set these variables, please refer to::
+
+ https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-gitlab-cicd
+
+Here is a list of the most used variables:
+
+QEMU_CI_AVOCADO_TESTING
+~~~~~~~~~~~~~~~~~~~~~~~
+By default, tests using the Avocado framework are not run automatically in
+the pipelines (because multiple artifacts have to be downloaded, and if
+these artifacts are not already cached, downloading them make the jobs
+reach the timeout limit). Set this variable to have the tests using the
+Avocado framework run automatically.
