[Search:WebCrawlers:ViewCrawler:Scheduling page]Success notification appearing after each change on Scheduling

[L1nBra]

Description
Success notifications should appear timely and not overwhelm user appearing after each and every small change.

Preconditions
Stateful Web Crawlers -> View Crawler -> Scheduling page is opened.
Web crawler is added
Use Screen Reader (NVDA).

Steps to reproduce

1.Navigate to Enabling recurring crawls... switch button using only keyboard by pressing Tab key.
2.Press Enter.
3.Observe the page and screen reader.
4.Navigate to Day field.
5.Press many times up and/or down arrow.
6.Observe the page and screen reader.

UI elements + NVDA Speech Viewer

Actual Result

• After each change: turning on switch, changing (selecting) day in the field - success message appears.

Expected Result

• Would be better if success message appeared after user finally changes all the settings in one panel.

Notes:
After each and every small change with every field in Specific time scheduling card, Interval scheduling card, even in case user accidentally presses/changes something - he/she always sees the success notification and hears about it.
