Fix es5 issues

[veger]

As requested in #182 a PR for the 5.x branch.

Copied description from #182:

In order to be able to install a Elasticsearch cluster using version 5.0.0, I had to add the following v5.x support (next to the other PRs I submitted today and yesterday):

• Use log4j2.properties instead of logging.yml - https://www.elastic.co/guide/en/elasticsearch/reference/5.0/settings.html#logging
• Add jvm.options - https://www.elastic.co/guide/en/elasticsearch/reference/master/setting-system-settings.html#es-java-opts
• Use bootstrap.memory_lock instead of bootstrap.mlockall - https://www.elastic.co/guide/en/elasticsearch/reference/master/setup-configuration-memory.html#mlockall
• Get rid of work directory - Remove working directory elasticsearch#10672
• Executable does not accept -D anymore, replace with -E and -p - --help of executable
• Executable does not accept -- anymore, replace with -E - https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_settings_changes.html#_removed_using_double_dashes_to_configure_elasticsearch
• Get rid of 5.x default (file)s - Similar to other package defaults

⚠️ I am absolutely no Elasticsearch expert (or a experiences user), so I added my references to the list of changes to show why I made the modifications

Additional remarks:

• I tried to keep ES < 5.x compatible, hence the version checks. If support for < 5.x is not required, I can remove the checks
• I do not know about (the/Ansible) role tests, so they probably break... I would appreciate it, if someone is willing to help, or point me in the right direction!
