Merge pull request #32359 from wojtek-t/rollback_etcd

Browse Source 
Automatic merge from submit-queue

Use etcd 2.3.7

This will switch to etcd 2.3.7 for release 1.4, to resolve issues rolling back from 1.4 to 1.3 (while preventing those same issues rolling back to 1.4.0 from a release including etcd 3.0.x).

Fixes #32253.

See #32253 (comment) for etcd roadmap.
