Updated drush.yml to ensure --extra flag set on all drush sql commands

[nicksantamaria]

Motivation

For some reason drush sql commands have become flakey and require the --extra='--disable-tls' flag. Unfortunately drush 13.4 does not support this flag for sql:drop (among others) which is breaking builds.

Changes

• Adds new version of drush.yml which adds the required flag to these options.
