google: Option to filter groups by regexp

[jfrabaute]

When fetching groups, this field allows to add a regexp to filter the groups
that will be returned and used.
This can be useful when the user is registered on a lot of groups because
he is part of multiple clusters. In this case, usually, the groups are named
with a pattern and a regexp can be used to filter the groups per cluster,
allowing to have a smaller group list retrieved for each cluster.
Default to empty string, and no filtering will be done in this case.

We are planning to implement something like this for all providers for quite some time. I've just opened the issue to track its progress: #1635

Personally, I'm against merging any more PRs adding per connector features. Would be nice to make this a top priority though.

Ping. Can we get this upstream pretty please?

Hi, is there some perspective on any kind of feature like that?

I also need similar feature to allow filter of groups or event better filter or regexp on any claim return by the upstream oidc.

Hell @alexisdondon. We are a bit out of track, but we look forward to implementing a generic option to mutate groups soon this year.
