Simple nodejs api that can perform the following tasks:

1. Accept a key(string) and value(some json blob/string) {"key" : "value"} and store them. If an existing key is sent, the value should be updated

2. Accept a key and return the corresponding latest value

3. When given a key AND a timestamp (as query string), return whatever the value of the key at the time was.

4. List all items.
