[IMP] base: change cache busting middleware

In the HTTP pipeline, there is a middleware called DisableCacheMiddleware
that is called on every request to check if we are in debug mode, to remove
the cache headers and replace them with a static 'no-cache' so the browser
has to contact the server and check for a new version of every ressouce.

There were 2 problems with it:
1. it was doing more work than strictly needed when not in debug, like
rebuilding a list of headers for every request
2. it was removing Etag (case sensitive) with a typo and other headers
that could have been left in place.

This commit fixes those 2 issues by only modifying the headers if we are
in debug mode, and only removing the header 'cache-control' and replacing
it with 'cache-control: no-cache'
