Sam Saffron 62141b6316 FEATURE: enable_performance_http_headers for performance diagnostics
This adds support for DISCOURSE_ENABLE_PERFORMANCE_HTTP_HEADERS
when set to `true` this will turn on performance related headers

```text
X-Redis-Calls: 10     # number of redis calls
X-Redis-Time: 1.02    # redis time in seconds
X-Sql-Commands: 102   # number of SQL commands
X-Sql-Time: 1.02      # duration in SQL in seconds
X-Queue-Time: 1.01    # time the request sat in queue (depends on NGINX)
```

To get queue time NGINX must provide: HTTP_X_REQUEST_START

We do not recommend you enable this without thinking, it exposes information
about what your page is doing, usually you would only enable this if you
intend to strip off the headers further down the stream in a proxy

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

I suspect this commit is preventing Sidekiq from running inprocess.

Sam c04bcf8655 PERF: move message bus to the front of the middleware stack
Organise all initializers so they are properly ordered and use the same naming scheme
