### What changes were proposed in this pull request?
* Pagination Support is added to all tables of streaming page in spark web
UI.
For adding pagination support, existing classes from #7399 were used.
* Earlier streaming page has two tables `Active Batches` and `Completed
Batches`. Now, we will have three tables `Running Batches`, `Waiting Batches`
and `Completed Batches`. If we have large number of waiting and running batches
then keeping track in a single table is difficult. Also other pages have
different table for different type type of data.
* Earlier empty tables were shown. Now only non-empty tables will be shown.
`Active Batches` table used to show details of waiting batches followed by
running batches.

### Why are the changes needed?
Pagination will allow users to analyse the table in much better way. All
spark web UI pages support pagination apart from streaming pages, so this will
add consistency as well. Also it might fix the potential OOM errors that can
arise.
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.

### Does this PR introduce _any_ user-facing change?
Yes. `Active Batches` table is split into two tables `Running Batches` and
`Waiting Batches`. Pagination Support is added to the all the tables. Every
other functionality is unchanged.
<!--
Note that it means *any* user-facing change including all aspects such as
the documentation fix.
If yes, please clarify the previous behavior and the change this PR proposes
- provide the console output, description and/or an example to show the
behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to
the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.

### How was this patch tested?
Manually.
I will update the Description with the before and after snapshots.
