Used to indicate if a vhost needs PHP configuration or not, like
for a static site. Set in the hosts's nginx_vhosts block. Defaults
to "False" if unset.

roles/nginx: Only check WordPress variables is vhost is using WordPress
This variable is used to control the FastCGI cache, and doesn't

roles/nginx: Use explicity booleans for tests instead of "yes" and "no"
Better to be explict with booleans rather than being confused when
you mix up yes and "yes" with Ansible/Python testing of conditionals.

roles/nginx: use boolean for use_letsencrypt instead of string "yes"
This is very confusing when you forget about how Ansible/Python is
testing conditionals. Let's use actual booleans so it's more clear.

roles/nginx: Add mitigation for HTTPoxy vulnerability
Malicious requests including the HTTP_PROXY value will be able to
manipulate some server-side libraries. Better to just block them
in nginx.

roles/nginx: Rework Let's Encrypt stuff
Take an opinionated stance on HTTPS and assume that hosts are using
HTTPS for all vhosts. This can either be via custom TLS cert/key
pairs defined in the host's variables (could even be self-signed
certificates on dev boxes) or via Let's Encrypt.

roles/nginx: Allow usage of Let's Encrypt certs
Hosts can specify use_letsencrypt: 'yes' in their host_vars. For
now this assumes that the certificates already exist (ie, you have
to manually run Let's Encrypt first to register/create the certs).

Rename nginx_* variables underneath nginx_vhosts
It's just deduplication, since it's already obvious that the dict
is for nginx-related vars:

    - nginx_domain_name→domain_name
    - nginx_domain_aliases→domain_aliases
    - nginx_enable_https→enable_https
    - nginx_enable_hsts→enable_hsts

Set `use_snakeoil_cert: 'yes'` in host_vars. This is good for dev
hosts where we don't have real domains or real certs. But everything

roles/nginx: Add HSTS check to vhost template
We need to actually check if HSTS was requested before setting the
header in the block handing PHP requests. We check in the main vhost
block, but nginx headers are only inherited if you don't set ANY
headers in child blocks (ie, headers set in parent blocks are cleared
if you set any new ones in the child).

roles/nginx: Move HTTP Strict Transport Security toggle to vhosts
This is really a per-site setting, so it doesn't make sense to have
a role default. Anyways, HSTS is kinda tricky and potentially dang-
erous, so unless a vhost explicitly sets it to "yes" we shouldn't
enable it.

Note: also switch from using a boolean to using a string; it is st-
ill declarative, but at least now I don't have to guess whether it
is being treated as a bool or not.

151fb29687 roles/nginx: Add blank vhost
For security and predictability clients should only get a reponse
if they request a hostname we are actually hosting.

If TLS is in use then this will use a self-signed snakeoil cert for
an HTTPS-enabled blank, default vhost.
