fix(deps): fix issues when running glide up

When running glide update there are errors due to pinned versions
in the glide.yaml file mixed with getting a more recent version of
kubernetes. client-go needs a newer version of go-autorest.

Note, go-autorest is pinned to v8.0.0 rather than the latest
release of v8.4.0 because kubernetes is pinned to v8.0.0.

no reason to populate it explicitly with its zero value.

add section on semantic versioning

Fixes #2888. Clarifies that use of default command should stay DRY

This documentation was ripped from the Helm v2.2.0 release notes. I've referenced it enough times that
it should be placed somewhere in the documentation.
