Support HAProxy Data Plane API v3 and fix unrelated build/crash bugs

Parameterize the Data Plane API version (api_version provider arg,
default v3) instead of hardcoding /v2/ in every request URL — current
dataplaneapi releases no longer serve /v2/ at all, which broke every
operation out of the box.

Also fixes two unrelated pre-existing bugs surfaced while testing:
- main failed to build due to a grpc/google.golang.org/api version
  conflict from a prior dependency bump; bumped google.golang.org/api.
- nil-pointer panics in ~33 resource/data-source Read/Create/Update/
  Delete functions whenever the underlying transaction request failed
  (the most common trigger being the /v2/ 404s above), matching the
  crash reported in #3.
