Analyzer logs\Analyzer done UI elements have too many entries

[rushattac]

Describe the bug After #1960 the tagger analyzer and feature extractor display an entire for every celery worker process based on the number of defined tags\features. which floods the UI for the analyzer logs and analyzer done.

To Reproduce Steps to reproduce the behavior:

1. pull latest timesketch
2. define x number of tags\features
3. run the tagger or feature extractor analyzer.

Expected behavior Regardless of the number of workers only a single entre is shown. maybe a status of workers done or still running could be added.

Hm, yea that is kind of WAI, a status of the worker would not solve it, because technically, there is a set of workers now and each shows the status.
