(...) for snippets filename.
BREAKING CHANGE: Users have to modify their pillar
according to this commit. Users MUST append '.conf' for their
existing managed snippets.

First implementation of TOFS for:
nginx_config, passenger_config, servers_config and snippets
Introduced tplroot on modified files as well
Fixed GH link of nginx.conf file in docs/TOFS_pattern.rst
Fixed test for snippets name pillar

* Route all to `nginx/deprecated.sls`

BREAKING CHANGE: all previous `nginx` based configurations must be reviewed;
`nginx.ng` usage must be promoted to `nginx` and any uses of the original
`nginx` will have to be converted.

In order to improve security and ease of use, added creation/generation
of dhparam file.
