Implement public rooms APIs (#185)
* Move events contents to common * Basic database structure * Complete database update * Support visibility update and retrieval * Add HTTP methods for visibility update and retrieval * Add the database for the new component * Add a listener for the new component * Fix attribute update statements * Create public rooms component * Fix failing test * Add roomserver consumer * Fix a bug in aliases creation * Add a check on type * Implement public rooms directory * Use auth API for visibility update * Support filtering * Add component to monolith * Various fixes * Fix computation of next public rooms batch * Retrieve state events from the roomserver query API + avoid dupes on join * Split update of string or boolean attribute in two separate functions * Use event type to detect duplicate joins * Improve the joined members counter computation * Use event.RoomID()
