    Description

      drobinson noticed retrieving metrics/snapshot statistics could be very inefficient.

      [user@server ~]$ time curl -s localhost:5050/metrics/snapshot

real	0m35.654s
user	0m0.019s
sys	0m0.011s

      MESOS-1287 introduces a timeout parameter for this query, but for metric-collectors like ours they are not aware of such URL-specific parameter, so we need:

      1) We should always have a timeout and set some default value to it

      2) Investigate why master metrics/snapshot could take such a long time to complete under load.
