de720e4f0a Cluster: send a ping to every node we never contacted in timeout/2 seconds. 
Usually we try to send just 1 ping every second, however when we detect
we are going to have unreliable failure detection because we can't ping
some node in time, send an additional ping.

This should only happen with very large clusters or when the the node
timeout is set to a very low value.

If we are a cluster node the DB content will not match our configured
slots. Don't do the check at all.

There are pathological cases where the line can be even longer a single
node may contain all the slots in importing/migrating state.

06fa5f82d7 SLAVEOF command refactored into a proper API. 
We now have replicationSetMaster() and replicationUnsetMaster() that can
be called in other contexts (for instance Redis Cluster).

824879435c redis-cli: use keepalive socket option. 
This should improve things in two ways:

1) Prevent timeouts caused by the execution of long commands.
2) Improve detection of real connection errors.

This is mostly effective only on Linux because of the bogus default
keepalive settings. In Linux we have OS-specific calls to set the
keepalive interval to reasonable values.

19833a01f2 Cluster: don't set the slot as unassigned because of PONG info. 
As stated in the comment this is usually due to a resharding in progress
so the client should be still redirected to the old node that will
handle the redirection elsewhere.

The new code makes sure that the node slots bitmap is always consistent

7348dbc52c Cluster: new field in cluster node structure, "numslots". 
Before a relatively slow popcount() operation was needed every time we
needed to get the number of slots served by a given cluster node.
Now we just need to check an integer that is taken in sync with the
bitmap.
