  1. Add soft TTL to Query Cache entries 

    When Query Cache entries reach the soft ttl, the next query hit the
backend and refresh the entry. While the refresh happens, other queries
keeps getting the "old" Query Cache entry.

Soft ttl is a percentage of the cache ttl and is defined by a global
variable for all the entries. If the value is 0, soft ttl is disabled
and no used.
