Don't raise MySQL 2013 'Lost connection' errors

cherry pick, including original commit message below from
oslo-incubator commit:

b4f72b2987d53bb434e3a833f06d70a2167f5efc

Closes bug: 1275838

Although this code error is part of the `ping_listener` tests, it was
missing from the list of known - and ignored - connection errors.

The code error 2013 refers to a connection lost during a query, see:
https://dev.mysql.com/doc/refman/5.0/en/error-messages-client.html#error_cr_server_lost

Without this error code, the session won't try to reconnect to mysql,
which makes `max_retries` useless.

Rename self.tgtadm to self.target_helper

Using "tgtadm" for this member variable is confusing because it
actually represents tgt, IET, and LIO.  Rename to a more generic
term to make things more readable.

Also remove "tgtadm" from method names and references in tests
where it is not tgtadm-specific.

I'm choosing the name "target_helper" because "tgtadm" = tgtd,
and "iscsi_helper" doesn't fit when using RDMA in ISERDriver.
