Latest push contains both simplification changes to
`NodeDecommissionMetrics` and `DatanodeAdminMonitorImpl` to use the
`ContainerStateInWorkflow` inner class and methods. Thanks for the suggestion.
Also included is a fix to the jmx by host metrics collected:
> The way I'd expect this to work is we have 1 tag per DN, and then the 4
metrics (under, sufficiently, pipelines, unhealthy) all sharing that tag.
example with datanode 1 and datanode 3 in decommissioning workflow as
captured by monitor:
```
"TrackedPipelinesWaitingToCloseTotal" : 4,
"TrackedContainersUnderReplicatedTotal" : 0,
"TrackedContainersUnhealthyTotal" : 0,
"TrackedContainersSufficientlyReplicatedTotal" : 0,
"tag.datanode.1" : "ozone_datanode_1.ozone_default",
"tag.Hostname.1" : "f27febaf1870",
"TrackedPipelinesWaitingToCloseDN.1" : 2,
"TrackedUnderReplicatedDN.1" : 0,
"TrackedSufficientlyReplicatedDN.1" : 0,
"TrackedUnhealthyContainersDN.1" : 0,
"tag.datanode.2" : "ozone_datanode_3.ozone_default",
"tag.Hostname.2" : "f27febaf1870",
"TrackedPipelinesWaitingToCloseDN.2" : 2,
"TrackedUnderReplicatedDN.2" : 0,
"TrackedSufficientlyReplicatedDN.2" : 0,
"TrackedUnhealthyContainersDN.2" : 0
