[CLI] Feature Request: cache for CLI

[pcorpet]

Description of the problem, including code/CLI snippet

Feature/Improve suggestion: I use the gitlab cli extensively in my flow and would strongly benefit a cache feature. It would work like this:

gitlab --cache 600 project-member list --project-id 12345

See https://github.com/github/hub/blob/d0e9e009ffc537c656a6cb8ec5cc132be5e4b8df/github/http.go#L400 for inspiration (the --cache feature on the hub tool, equivalent for GitHub).

Expected Behavior

Running this command twice in less than 10 minutes (600 seconds) would only query GitLab API the first time and return the same result.

Actual Behavior

The second command is as long as the first one.

Specifications

• python-gitlab version: 1.8.0
• API version you are using (v3/v4): v4
• Gitlab server version (or gitlab.com): gitlab.com

Hi, I've given this a go (for personal learning more than anything), I could push a draft if that's ok?
I used cachetools (https://cachetools.readthedocs.io/en/latest/) which is probably not ideal (importing new stuff), dunno if it can be useful nonetheless.

I'm not sure, if we really should blow up the CLI like that.

Maybe just write a Python script for your case.

Cool. I don't have a case either, I was just looking for stuff to try :)
