edxapp role won't put ELASTIC_SEARCH_CONFIG into cms_env_config

[bryanlandia]

This is important because if you host elasticsearch somewhere other than localhost, your CMS will not be able to access it to do indexing. I can get together a PR but need to update my local to Eucalyptus/master and branch from that first.

edx-platform has been fixed in commit https://github.com/edx/edx-platform/commit/5fe1a114eab55453525c8127854271637755c6fb to get a value for EDXAPP_ELASTIC_SEARCH_CONFIG from env_tokens.

My configuration repo is at https://github.com/edx/configuration@af01848b91a0b228a33da667f284c3dfacd66aba

Steps to replicate:

• run /edx/bin/update edx-platform
• check cms.env.json
• cms.env.json won't have a key for EDXAPP_ELASTIC_SEARCH_CONFIG
