Apply Apache license to all .go source files (closes #1865)
I am not a lawyer, but according to the appendix of the license,
these boilerplate notices should be included with every source file.

a50462974c Refactor and clean up policy code
This commit shouldn't change any behavior. It is simply a cleanup of
the different proxy policies. It also adds some comments explaining the
sampling method used, since on first inspection it might not appear to
be a uniformly random selection.

fee4890e94 Balance round robin evenly when some hosts are down (#880)
* Balance round robin evenly when some hosts are down

Before, when load balancing across multiple hosts, if a host went down
then the next host in line would be sent a double share of requests.
This is because the round robin counter was only incremented once per
request, regardless of the health of the selection. If current
selection was unhealthy then the policy would advance to the next host,
but this would not be reflected in the policy counter. To fix this, the
counter is now incremented for every attempted host.

This commit adds a test case that identifies the issue, and a fix.

* Make robin counter private

* Use a mutex to sync round robin selection
