BUG#44830 : SLAVE START no longer results in error if RESTORE is running on master
Disabled portions of rpl_backup test because the slave no longer
returns an error when a restore is in progress. This is a change
in the way the slaves connect to the master and must be fixed.
It has broken the ability to block slave connections (via START
SLAVE) while a restore is in progress.
Previously, when a slave attempted to connect to a master that
had a restore in progress, the START SLAVE command would fail and
an error would be sent to the client. Now, the command succeeds and
no error is sent to the client. Since this test relies on detecting
the error, it fails when run against the latest code.
It is likely the mechanism for how the slave connects and/or the
sequence of events for detecting errors has changed thereby
causing the slave to delay the detection of being blocked by a
restore run on the master.
