Review Comment:
In the upstream code the analyzer was `null` rather than `new
MockAnalyzer(Random)`. Looking at the `LiveIndexWriterConfig`, it should accept
that, although I am not sure about the code that uses `IndexWriterConfig`. Did
you try `null`, and if so, what happened?
If it doesn't work, then maybe we should patch this inside of
`NewSnapshotIndexWriterConfig` for the time being, since that will come up as a
new method that we need to port, anyway.
Either way, this diverges from upstream and we will need a `LUCENENET
UPGRADE TODO` comment (unless `null` works).

Review Comment:
`LUCENENET TODO` is generally reserved for work to do *prior to the 4.8.0
release* (except Ron also committed a bunch of them that will apply to an
upgrade just like these). We should have a different convention for future work
than for things that are pending for the current release. We specifically
mention in the CONTRIBUTING section that `LUCENENET TODO` are up for grabs, but
we definitely don't want this work done until later.
Maybe we should make it `LUCENENET UPGRADE TODO` to ensure it doesn't come
up in a search for `LUCENENET TODO` (and change all of those that Ron added as
well in a separate PR). It would then be easy to do a find and replace before
we begin upgrading to change them to `LUCENENET TODO`.
