Add the delete function

[HKayed]

Description
As a user, I'd like to have a delete function to delete the employees.

Acceptance Criteria

There should be two different variants of the delete function:

1. delete via swipe

• The desired employee can be deleted via swipe.

2. delete via kebab button

• In the kebab button there should be the function delete. When you click on the function, the delete function will be activated on the page. You can select one or more employees and delete them or there is an option delete all. If the delete function is not activated by the kebab button, then it is not displayed on the page and it is not possible to delete anything.
• When displaying the delete function, only one icon should be used. Before the delete process is completed, the user should be shown a warning that he is about to delete the user(s). To complete the deletion process, the user must confirm this warning. Furthermore, the user should be given the option to cancel the process.
• For the delete all function, there should be a text field next to the icon with the label delete all.
