Converting to go 1.11 modules

Removes vendored version of hysterix.

Initattes two new go module roots:
- One for the git root
- One for the examples/ sub-directory

Change example_test.go to rely on fewer external dependenceis.

Updates Travis Go version to 1.11, and enables go build cache for faster
CI runs.
