mysql: Implement and test COM_CHANGE_USER

Browse source 
This reworks the parser such that COM_CHANGE_USER switches the
connection back into the CONNECTION_PHASE so that we can remove the
EXPECT_AUTH_SWITCH special case in the COMMAND_PHASE. Adds two pcaps
produced with Python that actually do COM_CHANGE_USER as it seems
not possible from the MySQL CLI.
