On RedHat pgtune is incompatible with PostgreSQL 9.5

[mjuenema]

On RedHat family systems the pgtune tool will create configurations that are incompatible with PostgreSQL 9.5 as the checkpoint_segments parameter has been renamed to [min|max]_wal_segments. See also le0pard/pgtune#2.
The best work-around would probably be to not run pgtune if the PostgreSQL version is incompatible.

Same on Ubuntu

It seems that the original pgtune has been abandonded... but I did find a new project here:

https://github.com/le0pard/pgtune

It's not quite the same, so I don't know how much work it will be use that instead, or even if it's possible.

I'm working on #301 , which should achieve the goals of pgtune... but purely in Ansible, and is compatible with later versions of PostgreSQL.

It's not 100% tested yet, as I need to benchmark the suggestions on different server sizes.
