Ping leader in alluxio fs leader command

Description

The current behavior of

is to query Zookeeper for the address of the most recent leader.

The returned leader isn't necessarily running. This can be confusing to users. It would be helpful for the command to ping the returned leader address to check whether the leader is actually available. If it isn't, we can print a warning to stderr that the leader master isn't currently available.
