Summary:
On mac the curl command fails with error "A libcurl function was given a bad argument", but succeeds on retries so add a retry loop till it succeeds.

`curl_global_init` should be called before `curl_easy_init`. Adding a global helper to correctly initialize and clean it up in tests.

Re Enable all master path handler tests for mac.
