Currently it implements three subcommands:
PUBSUB CHANNELS [<pattern>] List channels with non-zero subscribers.
PUBSUB NUMSUB [channel_1 ...] List number of subscribers for channels.
PUBSUB NUMPAT Return number of subscribed patterns.

Sentinel was not able to detect slaves when connected to a very recent
version of Redis master since a previos non-backward compatible change
to INFO broken the parsing of the slaves ip:port INFO output.
This fixes issue #1164

When the semantics changed from logfile = NULL to logfile = "" to log
into standard output, no proper change was made to logStackTrace() to
make it able to work with the new setup.
This commit fixes the issue.

This feature allows the user to specify the minimum number of
connected replicas having a lag less or equal than the specified
amount of seconds for writes to be accepted.

There is a new 'lag' information in the list of slaves, in the
"replication" section of the INFO output.
Also the format was changed in a backward incompatible way in order to
make it more easy to parse if new fields are added in the future, as the
new format is comma separated but has named fields (no longer positional
fields).

Now masters, using the time at which the last REPLCONF ACK was received,
are able to explicitly disconnect slaves that are no longer responding.
Previously the only chance was to see a very long output buffer, that
was highly suboptimal.

ACKs can be also used as a base for synchronous replication. However in
that case they'll be explicitly requested by the master when the client
sends a request that needs to be replicated synchronously.
