TT#63000 db_redis: support range scans on timestamp keys

We introduce a special case handling of range matching (< or > operator)
against timestamp key values, as required by the usrloc module. Without
this, the timer handling the removal of expired location entries would
have to a full table scan every time it runs (including at shutdown).

This feature detects the special case (a usable timestamp key type) and
converts the range match into a series of wildcarded SCAN statements. So
instead of doing a single full table scan which mostly returns non
matching rows, we do a series of more specific table scans, each of
which only returns relevant matching rows, or no rows at all.

Change-Id: I6c77b9d595b5f70aed976bdcd0cae329f198937b
(cherry picked from commit 6df6f8718f)
