There are three "deeper" changes included with this update:
1) The `Detach` function got removed from the `StorageActionsService` in
favor of `DetachByDropletID` (which is now used in
`resource_digitalocean_volume.go`).
2) The `Update` function got removed from `TagsService` (renaming a tag
has been deprecated in the API).
3) Every function in godo now takes a `context.Context` as first
argument, so I've changed all calls to send in a `context.Background()`.
* 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.
