Paul Hinze 6fe2703665 Vendor all dependencies w/ Godep
* Remove `make updatedeps` from Travis build. We'll follow up with more
   specific plans around dependency updating in subsequent PRs.
 * Update all `make` targets to set `GO15VENDOREXPERIMENT=1` and to
   filter out `/vendor/` from `./...` where appropriate.
 * Temporarily remove `vet` from the `make test` target until we can
   figure out how to get it to not vet `vendor/`. (Initial
   experimentation failed to yield the proper incantation.)

Everything is pinned to current master, with the exception of:

 * Azure/azure-sdk-for-go which is pinned before the breaking change today
 * aws/aws-sdk-go which is pinned to the most recent tag

The documentation still needs to be updated, which we can do in a follow
up PR. The goal here is to unblock release.
