Merge branch '13333-consider-updating-http-parser-rb-to-0-6-0' into 'master'

Replace the tinder gem by bare HTTP requests

## What does this MR do?

It removes the `tinder` gem (used to talk to the Campfire API) and replaces its use by bare HTTP requests.

## Are there points in the code the reviewer needs to double check?

N/A.

## Why was this MR needed?

To simplify the potential dependency hell discussed in #13333.  
The initial issue was about updating `http_parser.rb` which was required by `twitter-stream` which was required by `tinder`.  
Those 3 gems are not needed anymore.  

## What are the relevant issue numbers?

#13333

## Screenshots (if relevant)

N/A.
