…mpaction strategies, also adding ttl and gc_grace. This fixes issue #215

lgtm, merging, thnx

resp. this sets retention of mms to only 20h (as per default_time_to_live = 72000 ) is it OK for the demo app?

maybe you can make the window 1 day and have 20 days TTL ? @guy9 ? (I lack mms app details, so not sure what is use case and if 20h are OK)

[tarzanek]

if semantics is ok, then please merge, syntactically it looks better and will work when running the demo ( cc @nopzdk thnx for the report/test)

Thanks!
