### Is your feature request related to a problem? Please describe the
problem.
`IndexWriter `can determine the order of concurrent index operations but
does not provide this information to the user.
### Describe the solution you'd like
Currently, `IW `can determine the order in which operations were executed by
updating the methods to return a long instead of `void`. If you are a caller
who does not require this information, you can ignore the returned `long`.
Additionally, this change enables the removal of the `TrackingIndexWriter
`wrapper class with similar functionality by returning a `long` for each
operation but with weaker guarantees.
### Additional context
For example, the below basic test returns the indexing in ordering with
incremental `seqNo`
```cs
[Test]
public void TestBasic()
{
Directory dir = NewDirectory();
IndexWriter w = new IndexWriter(dir,
NewIndexWriterConfig(TEST_VERSION_CURRENT, new MockAnalyzer(Random)));
long a = w.AddDocument(new Document());
long b = w.AddDocument(new Document());
assertTrue(b > a);
w.Dispose();
dir.Dispose();
}
