Default redis-sentinel config has incorrect comments

[James Howe]

The file /etc/redis/sentinel.conf is a self-documenting default config file.
However, a number of doc comments don't match the items.

In particular:
"sentinel myid" is documented as "sentinel monitor"
"sentinel monitor" is documented as "sentinel down-after-milliseconds"
"sentinel config-epoch" is documented as "sentinel parallel-syncs"
"sentinel leader-epoch" is documented as "sentinel failover-timeout".

On further investigation, the shipped config file is immediately changed when the service starts after installation, so it's an upstream bug in redis.
