When spawning Heat stacks, the DB reaches the max_connections limit. This causes MariaDB to block all traffic by source IP, essentially blocking all services. This patch introduces the MARIADB_MAX_CONNECTIONS parameter to make the max_connections configurable. The default of 151 max_connections is maintained. Closes-Bug: #1465422 Change-Id: I869aa9f117c6fa959b1c6948dfc379f30a6bc1d7
