Dear devstack team,

Recently, the ElasticSearch installation fails and that makes Freezer (e.g., [1]) or any other services that depend on ElasticSearch fail the CI tests. A preliminary investigation suggests that it may cause by the test environment was switched to Ubuntu 18.04 (i.e., bionic). I made some modifications to the installation script in [2] hopefully will fix the problem. If someone in the Devstack team can have look at [2], it would be great.
