Subject: [PATCH] Manage oslo_middleware/max_request_body_size

So that we can increase it from the default 114688

Useful in case for example the OS-Federation mapping is too large.

If this limit is breached heat will return a 413 Entity Too Large
and not log anything to heat.log.

Closes-Bug: #1835161
