411: print nicer error message when shared.key is not present
pylib: use a keep alive option in mysql connection

mysql has this "feature" that after 8 hours it drops a connection.
So for long running processes which uses database (aka airboss, etc.)
this was a problem.
This fix should not impact rocks command line
pylib: fix more escaping of attribute

forgot to escape attribute when generating kickstart graph
pylib: fix ordering in rocks dump

rocks set host boot should be dumped only after the network
interfaces have been created (added) and not before that.
If the interfaces are not present in the DB rocks set host
boot will fail.
