mod_http_oauth2: Add support for the "openid" scope
This "openid" scope is there to signal access to the userinfo endpoint,
which is needed for OIDC support.
We don't actually check this later because the userinfo endpoint only
returns info embedded in the token itself, but in the future we may want
to check this more carefully.

| 8 Introduction | |
| 9 ============ | |
| 10 | |
| 11 This module attemtps to provide a storage driver that is really multiple | |
| 12 storage drivers. This could be used for storage error tolerance or | |
| 13 caching of data in a faster storage driver. | |
| 14 | |
| 15 Configuration | |
| 16 ============= | |
| 17 | |
| 18 An example: | |
| 19 | |
| 20 ``` {.lua} | |
| 21 storage = "multi" | |
| 22 storage_multi_policy = "all" | |
| 23 storage_multi = { | |
| 24 "memory", | |
| 25 "internal", | |
| 26 "sql" | |
| 27 } | |
| 28 ``` | |
| 29 | |
| 30 Here data would be first read from or written to [mod\_storage\_memory], | |
| 31 then internal storage, then SQL storage. For reads, the first successful | |
| 32 read will be used. For writes, it depends on the `storage_multi_policy` | |
| 33 option. If set to `"all"`, then all storage backends must report success | |
| 34 for the write to be considered successful. Other options are `"one"` and | |
| 35 `"majority"`. |
