Download, and install elasticsearch server for freezer-api
In devstack/pkg, there is an elasticsearch.sh for downloading, installing, starting and uninstalling of elasticsearch server, but it is not flexible. In the future, freezer-api needs to support ubuntu-xenial and ubuntu-bonic, which requires different elasticsearch server versions. In addition, the programming interface of elastic search server varies greatly before and after 5.0.0, which requires different code of freezer-api to support. Pre-5.0.0 version of elasticsearch server cannot be installed on ubuntu-bonic. For the convenience of modification, freezer-api maintains the elastic search.sh script by itself.
