Using the tile38-cli, the TTL command omitted the ttl value from the
json response.
For example:
127.0.0.1:9851> TTL my ufo
{"ok":true,"elapsed":"5.57µs"}
Is now fixed to show
127.0.0.1:9851> TTL my ufo
{"ok":true,"ttl":-1,"elapsed":"5.57µs"}
Where "ttl" is the remaining time before the object is is deleted.
The value -1 means that the object is available, but does not have
an expiration.
Thanks @phulst for finding this bug. closes#116
