[PATCH v3 5/5] gitlab: support disabling job auto-run in upstream

[Daniel P . Berrangé]

In forks QEMU_CI=1 can be used to create a pipeline but not auto-run any
jobs. In upstream jobs always auto-run, which is equiv of QEMU_CI=2.

This supports setting QEMU_CI=1 in upstream, to disable job auto-run.
This can be used to preserve CI minutes if repushing a branch to staging
with a specific fix that only needs testing in limited scenarios.
