not sure we really need this linebreak I believe we need to wait until screen ready first TOPIC_TO_RETAIN_DATA rename to cameCase pls
for example -> topicWithTimeToRetain let's keep a single style in namings. all topics in this class are named using next pattern: topic-name-randomAlphabetic(5) Deleted  added  Yes , it*s not a constant variable , refactored  changed to randomAlphabetic(5)
[e2e]Checking "Time to retain data (in ms)" custom value with editing Topic's settings
Autotest implementation for:

https://app.qase.io/case/KAFKAUI-266

Description:
Purpose of this case is to check custom "Time to retain data (in ms)" to not be default value always

Pre-conditions:
Login to https://www.kafka-ui.provectus.io/

Post-conditions:
Empty value

Steps:
1. Navigate to Topics from left navigation bar
2. Add a Topic
Expected result:
Topic form should open with "604800000" default value for "Time to retain data (in ms)"
3. Fill Topic name
4. Change "Time to retain data (in ms)" value
Input data:
"86400000" 1 day
5. Press "Create Topic"
Expected result:
New created Topic profile should open
6. Select "Edit settings" from menu icon
Expected result:
Custom "86400000" value for "Time to retain data (in ms)" should be displayed instead of default value
