Getting connection resets intermittently when making rally calls

[recaph]

Problem:
We make multiple requests to rally to get testcase inputs from rally and execute testcase on a GCP VM and then upload the results to Rally. Similar requests seem to work for some test cases during the same run, but some random test case fails to make connection with rally.
