Recording map related statistics

[farooqkz]

I think it's a good idea to record statistics about maps and their play sessions including but not limited to:

• Length of each session
• Average number of players in that session(can record number of players each minute since the beginning)
• Average K/D of players in that session
• Total attempts in that session
• Was the session skipped?
• Start session timestamp
• Game mode

I'd say save this data in Redis and make it accessible through a public API.
