Content API timeout exposé

This removes the current logging that I had been doing in code specific to Facia, and instead moves it upstream as far as the content API client.

This is obviously only for content API queries, and there are probably other call outs that have no logging, but I have decided to have this exposé on content API queries only by going upstream from everything on them.

If you would prefer the logging not to happen here, then please say why, and I will consider moving the logging to more specific points.

Here is a fun(???) test: Checkout this branch, run front.
tail frontend-front.log -f | grep java.util

Enjoy!
