Bug 1926258

Backporting to 4.7 pre-GA to reduce overall flakiness (and this will go back to 4.6 as well.

+++ This bug was initially created as a clone of Bug #1920221 +++

The e2e tests fork and run child tests in individual processes, which causes cloud provider initialization code to be run once per test, not once per suite as per upstream.  The GCP cloud provider makes several calls to initialize zones and other values that are constant over the life of a test run, and when lots of GCP tests are running at the same time we stand a chance of exceeding the burst quota on our account.  Every week or so we get a big chunk of failures as a result in our CI runs like:

This fails about 20% of GCP jobs total every week in the conformance suite, which impacts both PRs and release periodics.  This is intermittent.

The ideal fix is to have the cloud provider data seeded via environment and avoid duplicate initialization, which will require us to carry a patch to initialization to extract and reuse the value (during initCloudProvider, probably).  Should be possible to get that upstream in some form, but mitigating the impact quickly is important.
