Don't require `enabled: true` - helps distributions without
separate available/enabled directories and prevents error:
"Rendering SLS 'production:nginx.servers' failed: Jinja variable 'list
object' has no attribute 'enabled'"

nginx.servers_config wants a lightened copy of the nginx map
to render as json; but, when it was trying to remove the
servers and snippets keys from the map it assumed their presence,
causing a KeyError if they were not present by its use of .pop().
While wrapping these in an "if" clause would likely be more
correct, along with replacing .pop() with del (if jinja even
supports that) the simplest change here is to just specify a
default value for .pop(), which obviates the KeyError.
Fixes#274
* servers_config should run without service dependency. Service is
managed in servers.sls.
* dropped nginx_service_reload in favor of extending nginx_service
* wait for all file states (create and delete)
* create dirs for symlinked files
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
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.
