Create storage lenses and groups in data #512
Description
It seems like storage lenses (we already have an "all-buckets" one) and storage lens groups could be used to give us quick metrics down to an "ctotso" v "oncoanalyser" level without too much effort).
Even just enabling advanced analytics on our existing storage lens would give us metrics on data in/out.
Am only recommending us considering it for our major data storage accounts.
(it seems like there is terraform support for this config rather than me click-opsing it - though we might want to click-ops something first to explore what is possible)
