Create a common function to write resulting JSON files to the releases directory.
It makes this task simpler to read and maintain, while making it modifiable at a central point in the future.
One example of such modification could be the sorting of the versions in a uniform way for all the scripts.
This creates a common function to fetch HTTP URLs, with enhanced capabilities (retry, use of a known User-Agent).
It makes scripts that need those capabilities simpler, while improving other scripts.
This commit also fixes some scripts that did not log properly (cos.py, eks.py, haproxy.py, palo-alto-networks.py, rhel.py, ros.py, unrealircd.py).
This uses the PHP releases API. Limitations:
1. New Major versions will needed to be added manually
The src for the API is at https://github.com/php/web-php/blob/master/releases/index.php
The data comes from https://github.com/php/web-php/blob/master/include/releases.inc
This commit keeps the old sort method for a cleaner diff. Next commits
in this PR will fix the sorting to be standardized.
The difference from using tags is:
1. One additional version shows up (4.0.4) which we'd missed previously
due to being tagged as php-4.0.4REL.
2. Slightly more accurate dates.
