Wait for CI to pass checks happen too fast for Jenkins plugin

[tegankr]

We have encountered this issue when using marge-bot:

• wait_for_ci_to_pass function is executing before our jenkins external pipeline job is registered in GitLab
• this causes merge to fail because no pipeline is registered in time (we have pipelines must succeed set)
• we have a workaround by adding a 60 second pipeline job to keep the pipeline in a running state while we wait for the jenkins job to register in GitLab

Our setup:

• Jenkins GitLab Branch Source plugin listens to events sent via GitLab webhooks
• GitLab Jenkins webhook in GitLab triggers events on Push events (branches) and Merge Requests
• We do not have an actual GitLab pipeline job in our gitlab-ci.yml that triggers the jenkins job, it happens via the webhook.
• Pipelines must succeed + skipped pipelines are considered successful

Can we please introduce a wait time argument that will wait a given period of time prior to doing any CI checks?
