mod_delegation: use clean_xmlns to remove jabber:client namespace from node:
for the same reason as in mod_privilege, `jabber:client` namespace is removed with the
clean_xmlns method coming from there.
Furthermore, the forwarded <iq> stanza use the `jabber:client` xmlns while the stanza may
come from a component with e.g. `jabber:component:accept` xmlns, this can lead to
inconsistencies between the <iq> stanza and children (like <error> element).

--- 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"`.
