test: deflake gc-http-client tests by restricting number of requests

nicksia-vgw · danielleadams · commit 7007a9fd1b49 · 2022-08-15T20:38:58.000-04:00
sequential/test-gc-http-client tests were sometimes failing due to a non-deterministic number of requests being created, causing the test to fail on some systems with a "ECONNRESET" error caused by too many concurrent connections Fixes: #43638 PR-URL: #44146 Reviewed-By: Luigi Pinca <luigipinca@gmail.com> Reviewed-By: theanarkh <theratliter@gmail.com> Reviewed-By: Mohammed Keyvanzadeh <mohammadkeyvanzade94@gmail.com>
