### Description of PR
https://issues.apache.org/jira/browse/HDFS-16242
JournalMetrics should add JournalId MetricTag to distinguish different
nameservice journal metrics when JournalNode use ganglia sink or prometheus
sink.
JMX
Before this patch, journal' jmx :
// jmx json
{
"name" : "Hadoop:service=JournalNode,name=Journal-nntest1",
"Syncs60sNumOps" : 0,
...
},
{
"name" : "Hadoop:service=JournalNode,name=Journal-nntest2",
"Syncs60sNumOps" : 0,
...
}
After this patch, journal' jmx :
// jmx json
{
"name" : "Hadoop:service=JournalNode,name=Journal-nntest1",
"tag.JournalId" : "nntest1", // add this tag
"Syncs60sNumOps" : 0,
...
},
{
"name" : "Hadoop:service=JournalNode,name=Journal-nntest2",
"tag.JournalId" : "nntest2",
"Syncs60sNumOps" : 0,
...
}
PrometheusSink
Before this patch, journal' prometheus export :
journal_node_syncs60s_num_ops{context="dfs",hostname="host"} 2
After this patch, journal' prometheus export :
journal_node_syncs60s_num_ops{context="dfs",journalid="nntest2",hostname="host"}
2
journal_node_syncs60s_num_ops{context="dfs",journalid="nntest1",hostname="host"}
75
### How was this patch tested?
