Improve online archive Status
add more to the status of the online archive - for example, if I set it to 7days back it's good to know that currently at 80days.
An example: for a very big collection it takes long time to archive - so either show a % left until it caught up or show number of days currently at
other nice details: number of documents archived, archive rate, etc
I currently only have the hunch that it's working properly but the only information that I have is collection size is "not increasing quite as fast" as before the online archive was set. Would love to see some status / progress.
