==== CL 12839 ====
@FIX: install_worker.ubuntu would halt the installation process if the "qubeproxy" user exists but is not in /etc/passwd (which is valid when using networked authentications such as NIS and LDAP)
==== CL 12837 ====
@CHANGE: Linux supervisor install scripts fixes
@FIX: added code so that the install_supervisor.ubuntu script will not halt the entire installation if mysqld wasn't already running
@FIX: Removed stale code that added GRANT for root@'%'
==== CL 12831 ====
@FIX: added fix to work around a MySQL issue on Linux, where Unix socket connections can corrupt queries passed into it, making jobs disappear from GUI, or otherwise leave them in odd states ("failed" jobs with "running" instances, etc.)
The fix prohibits the use of Unix sockets on Linux, by overriding the value
of "database_socket" if set, and by disallowing setting "database_host" to
"localhost" in qb.conf
Also changed the default values of database_host to "127.0.0.1" and
database_socket to "" on Linux.
Modified so that the database parameters (not all) are printed to the
supelog and in the output of "qbadmin s -conf".
