refs #1: define configuration in one place and reuse it in several components
fixes #12
refs #12: mysql configuration is now handled by the mysql image
Fix wording
externalize elasticsearch communication/discovery port
reuse app_port variable
refs #12: build from lgueye/mysql, fix wording, simplify docker file
refs #12: now mysql components provisioning is handled by lgueye/mysql, this playbook only takes care of app db configuration
refactor: externalize mysql port, externalize index ports, remove es version (handled now by lgueye/elasticsearch image), set docker commands and ports for components index and data) at runtime rather than at build time for better control
refs #12: reuse lgueye/elasticsearch, simplify Dockerfile
refs #12: remove install instructions from playbook (now handled by lgueye/elasticsearch), keep configuration instruction (better responsibility splitting)
refs #12: remove es_version from vars (es_version is handled by base image lgueye/elasticsearch)
change app container wait time
