mod_http_oauth2: Only require redirect URIs when using grant types that need it
In the Device flow, no redirect URI is used because the client instead
receives responses by polling. It is therefore unnecessary to enforce a
requirement that these include redirect URI(s).

--- summary: Multi-backend storage module (WIP) labels: - NeedDocs - Stage-Alpha ... Introduction ============ This module attemtps to provide a storage driver that is really multiple storage drivers. This could be used for storage error tolerance or caching of data in a faster storage driver. Configuration ============= An example: ``` {.lua} storage = "multi" storage_multi_policy = "all" storage_multi = { "memory", "internal", "sql" } ``` Here data would be first read from or written to [mod\_storage\_memory], then internal storage, then SQL storage. For reads, the first successful read will be used. For writes, it depends on the `storage_multi_policy` option. If set to `"all"`, then all storage backends must report success for the write to be considered successful. Other options are `"one"` and `"majority"`.
