[ MO ] Warnings fix

[yekruglov]

Root cause analysis: Python interprets \ like regular expression pattern in docstring and raises a lot of warnings. So in some cases it can be difficult to read a log

Solution: Declare each docstring with \ as a row string by prepending r before it

Ticket: 49765

Why don't you cover all files?

Why don't you cover all files?

It is pointless and will take a lot of time. I only covered the files, where it was necessary

I disagree because it seems to me that this approach must be established on the regular basis because comments for transformations are regularly updated, new transformations along with comments are added, and other service mark symbols may affect. So your fix can be potentially broken in future.
