Add the ability to pass a precondition in an autotest so that it is displayed in allure

[Cameback]

Is your feature request related to a problem? Please describe.
I can't add precondition in my autotest (step my autotest and text message). Therefore, it is sometimes difficult for a tester to understand what belongs to the test and what to the precondition.

Describe the solution you'd like
Add the ability to add a precondition. So that this is displayed correctly in allure
await precondition('add precondition')
