util.datamanager: Disable blockwise removal In desperate need of tests

mod_muc: Use enum config API for 'restrict_room_creation' This communicates the accepted values in case the config diverges from them. Note that older documentation used an "admin" value behaving like an alias to true, but this is no longer handled. Should it?

plugins: Use get_option_array for some list shaped options Passing something from module:get_option() to ipairs() suggests that the option is a list of some sort.

util.datamanager: Disable block alignment Until we have more test coverage. Somehow the index becomes incorrect after inserting padding, unclear why.

plugins: Handle how get_option_period returns "never"

plugins: Use boolean config method in some places Because it makes sense and improves feedback via logging

mod_storage_internal: Use integer option method for cache size Missed this one in previous sweep

mod_muc_mam: Use period option method

mod_muc: Use enum option method for 'muc_room_default_presence_broadcast'

mod_storage_xep0227: Use enum option method
