Improvements

- Authorization is now required for the /info API method.
This method did not check authentication previously. This change is
backwards compatible with Tableau clients.
- Improved config parsing flexibility. Previously the
TABPY_EVALUATE_TIMEOUT setting would be set to a default if
tabpy couldn't parse the value. Now it will throw an exception
at startup.
