Description

Currently, the set ttl or unset ttl statement could only with a storage group path. However, this may cause trouble when having many storage groups.

So, it's better to set/unset TTL on any prefix path, we find the storage group under this prefix and set/unsert the TTL.

For example, we have storage group: root.a.sg1, root.a.sg2, root.b.sg3, root.b.sg4.

set ttl to root.a 1000 will set 1000 to root.a.sg1 and root.a.sg2.
