Add resoure lock mechanism

[sschnabe]

I have a service called dockerd and a step using this service (on kubernetes agent):

services:
  - name: dockerd
    image: plugins/dockerd
    privileged: true
    ports: [2375]
steps:
  docker-cli:
    image: plugins/docker-cli
    environment: [DOCKER_HOST=tcp://dockerd:2375]
    commands: [docker pull rancher/k3s:v1.24.12-k3s1]

This works fine for a single workflow. But if multiple workflows are running (e.g. multiple pull requests) all workflows except one are failing because the service already exists. Is there any method to prevent this? E.g. like Gitlab resource_groups?

I actually think workflows should not block each other in general.

It, probably, worked, when service name was unique. I am not sure because there is also the same port.

#3288 is fixed, is this still an issue?

[sschnabe]

I've not tested it yet, but i think this should fix my issue.

Did you test in the meantime?

Yes, my issues was solved with 2.4.0
