## Description
MySQL datasource config has a field called `Connection mode`, which
allows users to configure their datasource either in read write / read
only mode. This is supposed to block the write queries if datasource is
configured with read only mode, but with current implementation, it does
not block, it lets us execute write query.
On checking the codebase, it seems that this field is not at all being
used in mySQL plugin to configure the datasource, further more mysql
driver used may not even support configuring connection mode as of now,
hence as preventive solution, hiding the connection mode form config for
now.
