Create common functions parse_date, parse_month_year_date and parse_datetime.
Those functions support trying multiple formats, and come with default formats lists that support most of the date format encountered so far.
Notable change: year-month dates are now set to the end of month (impacted couchbase-server and ibm-aix).
When a ChunkedEncodingError occurs, request and response are not set and there is no way to get the URL that causes the error.
With this change all URLs are retried. The max_retries parameter is decreased each time so that we do not get stuck in an infinite loop.
I also considered to also wait before retrying, but for now I don't see any benefit to it.
Relates to #188.
Use the new endoflife.fetch_urls to fetch URLs. This is a bit more efficient, especially when network is slow.
Also update the way rows without a proper date format are excluded by checking the format first. I don't know why, but this fixed a bit the script, as now the 6.2.1 is properly retrieved and parsed.
Intermittent ChunkedEncodingErrors occurs while fetching URLs. This change try to fix it by retrying.
According to https://stackoverflow.com/a/44511691/374236, most servers transmit all data, but that's not what was observed.
For future reference the traceback was:
```
During handling of the above exception, another exception occurred:

Move the parallel URL fetching from firefox.py to endoflife.py to make available parallel URL fetching for all scripts.
Also a a fix found on https://stackoverflow.com/a/44511691/374236 to avoid ChunkedEncodingError.
