In particular we're interested in allowing local health checks with
consul without the need to configure TLS in the consul agent.

Also allows this to be disabled or configured to another value

* Adds git-receive pack to the existing list of paths that disable nginx
request buffering
* Makes the path configurable in attributes for overrides

After a discussion in https://gitlab.com/gitlab-org/gitlab-ce/issues/33719#note_67995336, we
agreed to enable it in light of performance and security concerns. Users may disable this
if they choose.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/33719

* Add /.well-known location to port 80 server directive
* Make production certificate notify to reload nginx, rather than run
reload every time.
* Add missing chain resource to acme_certificate calls
* Switch warning message to use ruby_block instead of ruby, so it isn't
run every time

* Use GitlabRails.public_path library method instead of adding on
the public_path attribute
* Move error code generation logic out of template and into library
method
* Update test to assume default value for errors on standard test
* Break apart tests for checking nginx config lines, and generation
* of error templates to separate sections.

* Uses a template, with configuration options as the content for the
messages to allow user to provide custom messages for specific http
errors.
* Ensures that 404, 422, 500, 502 are still handled if no customer
error is provided for those
* Issue 1323

Default real_ip_header and real_ip_recursive to nil in gitlab.rb. NGINX defaults will be used.

Otherwise this might 'hide' problems
