Due to security concerns, go1.17, even though very reluctantly,
similarly to Python broke backward compatibility and stopped to treat ';'
as separator when parsing URL queries.

We still want to accept ';' as separator in credential part.
-> Work it around by replacing ';' -> to '&'.

See https://golang.org/doc/go1.17#semicolons and https://github.com/golang/go/issues/25192 for context.
