Description
The Python SDK seems to take a long time to time out when ARVADOS_API_HOST is unreachable:
$ time arv-user-activity --days 1
Traceback (most recent call last):

Updates at 80f26d7 - branch 17171-pysdk-timeout-fix
Test run: developer-run-tests: #2416
- Fixes the bug by removing the default timeout value (5 minutes) of
arvados.api(), it's left to the callers the option to set it depending on the different needs. - Adds test.

review @ 80f26d7ffad85dc15a89bbf6f33a66e206832704
time arv-user-activity --days 1
takes a lot if None is there.

Thanks for spotting my mistake, I was doing manual tests with low values and assumed setting it to None would be equivalent.
After further investigation I realized that this wasn't a regression from 71e0f70a3095f669e4b136c9d7624c26634db0d3 but it was a real bug.
AFAICT, when passing None as a timeout to httplib2, it uses the socket module's default, that seems to be "no timeout": https://docs.python.org/3/library/socket.html#socket.getdefaulttimeout
Updates at aa8cdf27e sets arvados.api() default timeout to 10 seconds. Test updated to check for that.
