Admin Token: Identify SCIM Tokens
### Proposal
The [`Admin Token API`](https://docs.gitlab.com/ee/api/admin/token.html) allows getting information about arbitrary tokens. It can be used in to identify what a token does, e.g. in the context of leaked tokens.
It currently lacks support for `SCIM tokens` for identification, as well as revocation. See the [current implementation status](https://gitlab.com/gitlab-org/gitlab/-/issues/443597#implementation-status).
```
POST /api/v4/admin/token
```
Should return information about the SCIM configuration that is associated with the token.
