Should we have a 'test' jenkins server for experiments?

[sxa]

I need to request a new machine:

• New machine operating system (e.g. linux/windows/macos/solaris/aix): Probably linux
• New machine architecture (e.g. x64/aarch32/arm32/ppc64/ppc64le/sparc): Doesn't matter
• Provider (leave blank if it does not matter):
• Desired usage: Test jenkins server
• Any unusual specification/setup required: jenkins :-)
• How many of them are required: 1

Please explain what this machine is needed for:

• Initially proposed in Secure the public Jenkins server #2108 it would be useful to have a second server for people to experiment with before deploying to our production one. This may also allow us to restrict the access controls on the production server a bit more.

We would need to give careful consideration to:

• How many of the jobs are "live" on the test server (We would probably not want them triggering full build pipelines every day)
• Which nodes to attach to them (We don't want it to conflict with the production server)
• Which secrets will be available to jobs running on the server
