When adding Tugboat, also add drush.yml to generate drush uli ready links

[beto-aveiga]

We need a file drush.yml with:

options:
  uri: ${env.TUGBOAT_DEFAULT_SERVICE_URL_PROTOCOL}://${env.TUGBOAT_SERVICE_HOSTNAME}

And move it (could be in the online step)

      - cp "${TUGBOAT_ROOT}/.tugboat/drush.yml" "${TUGBOAT_ROOT}/drush"

So we can have ready login links in Tugboat.

Those changes can be included when Drainpipe manages Tugboat.
