Plans to support 6.x

[botzill]

Hi.

I tried to install 6.x version using the following settings:

es_version: "6.0.0-rc1"
es_major_version: "6.x-prerelease"

but seems to not be able to install it, es does not start.
I'm testing this on Debian.
Any plans to support 6.x version ?

1. elasticsearch-systemd-pre-exec was removed in 6.x (elastic/elasticsearch@9d8f11d#diff-4a4d0518983ac4a587c14d372df2e241) meaning systemd scripts would fail

   ansible-elasticsearch/templates/systemd/elasticsearch.j2

   Line 20 in 23abae8

   ExecStartPre=/usr/share/elasticsearch/bin/elasticsearch-systemd-pre-exec

2. default.path.data & default.path.conf are gone, Remove default path settings elasticsearch#25408, see new startup scripts in https://github.com/elastic/elasticsearch/tree/6.0/distribution

Fixed it, there are not too many changes to adapt this ansible role for ES 6.x
