Set the value to use for the "User-Agent" header on classMessages sent
from session.
If user_agent has trailing whitespace, session will append its own product
token (eg, libsoup/3.0.0) to the end of the header for you. If user_agent
is null then no "User-Agent" will be included in requests. See
propertySession:user-agent for more information.
