  upgrade to Train might fail due to mariadb row format

Bug description:
  In kolla-ansible CI we started getting on Ubuntu for Stein->Train:
  Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
  for "ALTER TABLE instances ADD hidden BOOL" in nova upgrade

  This is due to the following:

  ...
  If the table is using either the REDUNDANT or the COMPACT row format, then one potential solution to this problem is to convert the table to use the DYNAMIC row format instead.

  If your tables were originally created on an older version of MariaDB
  or MySQL, then your table may be using one of InnoDB's older row
  formats:

      In MariaDB 10.1 and before, and in MySQL 5.6 and before, the COMPACT row format was the default row format.
  ...
  from https://mariadb.com/kb/en/library/troubleshooting-row-size-too-large-errors-with-innodb/#solving-the-problem

  Indeed, the Stein images for Ubuntu include MariaDB 10.1 which we had
  to upgrade in Train due to other incompatibilities (with neutron).

  It is also worth noting that old CentOS deployments may also have this
  limited row format.
