Configurable history retention limits for rooms

[ara4n]

there doesn't seem to be a riot bug to track the need to define a configurable retention limit for a room, as needed for compliance and other enterprise uses.

I've P3'ed this for now; obviously this is a hard requirement for enterprise use so this will very likely become higher priority in the future.

An option to set the number of messages, or amount of days until messages 'expire' would be lovely.

At the moment Riot accumulates all chat history forever, which can be annoying and sometimes bad for privacy.

This is pretty close to element-hq/element-web#3104 (but this has a few more 👍s)

Support for this was added in synapse with 1.7.0rc1

this is major blocker before many homeservers can rollout message retention.

room admins must be able to configure room retention straight from client and users must be able to see current retention policy.

please make it happen. who I have to pay to get this?

Is there documentation where to set this in the ui?
