Bug Description

Detailed bug description:
 Murano environment with 19 applications got stuck during deployment process
Steps to reproduce:
 Add a large number of applications in a Murano environment and deploy it
Expected results:
 The environment should be deployed successfully
Actual result:
 The environment got stuck
Reproducibility:
 Personally I could not reproduce this bug since do not have enough hardware resources to launch a large number of applications.
Workaround:
 I presume that the error happens because the 'description' column in the tables 'environment' and 'session' is a TEXT datatype. The value that was inserted in this case is 70162 bytes long. As a workaround it might be useful to alter the tables and to set a MEDIUMTEXT datatype.
Impact:
  Customer cannot deploy large Murano environments
Description of the environment:
- Operation system: Ubuntu 14.04
- Versions of components: MOS 7.0
- Reference architecture:
- Network model: Neutron
- Related projects installed:
Additional information:
The log file is attached.

Sorry, made a mistake. The Murano system administrator had an environment with 19 applications initially. Then he decided to add four more applications and to deploy the modified environment.

Increased the size of TEXT columns to store large object models

Object model is stored in database in the columns of type TEXT. In
MySQL database this type of column is limited by default and cannot
hold data structures which are large enough.

This patch adds an extra migration which alters appropriate columns in
database when the mysql is used. The column type is explicitly set to
LONGTEXT.
