Requests which have response status codes in the inclusive ranges [(301..303), (305..399), (401..404)] will no longer create transactions by default. See config.trace_ignore_status_codes below to control what gets traced.
Stacktrace truncation for oversized events now takes 500 frames on each side instead of 250.

Features

Add config.trace_ignore_status_codes to control which response codes to ignore for tracing (#2725)
You can pass in an Array of individual status codes or ranges of status codes.
```
Sentry.init do |config|
    # ...
    # will ignore 404, 501, 502, 503
    config.trace_ignore_status_codes = [404, (501..503)]
end
```
Add config.profiles_sample_interval to control sampling frequency (#2745)
- Both stackprof and vernier now get sampled at a default frequency of 101 Hz.
Request body reading checks for :rewind to match Rack 3 behavior. (#2754)
