[pxapi] Allow streaming queries to reconnect if stream ends without t…

…railers (#1227)

Summary: The `perf-eval` github action was often failing because the
data loss streaming pxl script would fail with error "server closed the
stream without sending trailers". It seems like this happens similarly
to `RST_STREAM` when someone on the TCP chain decides to give up on the
connection. This diff allows the script to try to reconnect if this
error occurs. I tested the perf eval using these changes and it no
longer errors with the above error.

Type of change: /kind cleanup

Test Plan: Tested a perf eval with a streaming query and saw that it
successfully completed without running into any "server closed the
stream ..." errors.
