Accumulo has a shell command to list tablets. Below is an examplle output
from this command for a table created by the bulk RW test.
```

The new per tabet hosting goal could be added to this command. The
implementation of this command uses internal APIs and therefore getting this
information via public in jshell is not possible. In addition to adding the
hosting goal to this command output we could possibly create a public API for
getting this information. One way to do this is to generalize the new API
introduced in #3451 to get more per tablet info than just the hosting goal.
Something like the following.
```java
// this could replace the new HostingGoalForTablet class and add more
information
public interface TabletInformation {
TabletHostingGoal getHostingGoal();
TableId getTabletId();
String getLocation();
TabletHostingStatus getTabletHostingStatus();
//etc
}
interface TableOperations {
// replace the getTabletHostingGoal method with the more general method
that gets hosting goal plus other tablet info
Stream<TabletInformation> getTabletInformation(String tableName, Range
range);
}
```
