Update scaling polling interval

Polls every 100 ms instead of every 50ms for use with a new
faas-netes PR:

https://github.com/openfaas/faas-netes/pull/726

The call is much faster now, so this request should me made
at a lower frequency.

Also adds error handling for URL building in the external
service query code.
