So it doesn't get overlooked: asadmin tool sends client and server output to std
out/err, and upgrade tool parses this info. The server output includes log level
information and the tool can automatically check this for SEVERE messages to
warn the user. Info from the asadmin client side does not contain this
information, and isn't in the server.log file.
So the upgrade tool should send the client log information to the upgrade.log
file so it's not lost. While the info can't be automatically parsed, at least
it's there for the user in cases where, for instance, asadmin exits with a non
zero exit code.
