Investigate errors in fetching.log

[wurstbroteater]

Sometimes fetchers are unable to collect data. The following reasons are listed in fetching.log:

• <urllib3.connection.HTTPSConnection object at 0xee573ec8>: Failed to resolve 'www.google.com' ([Errno -3] Temporary failure in name resolution)
• SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1123)')
• Timed out receiving message from renderer: 294.352 (Selenium)
• Message: no such element: Unable to locate element: {"method":"xpath","selector":"//div[@class="delta rtw_temp"]"} (Selenium)
• invalid literal for int() with base 10: '' (Selenium)

Should fetchers be restarted after X time or just skip and hope next fetch in 10 minutes works. (=current state).

Easy solution: Blame ISP
