This fixes a crash in the grpc_performance_profile_* and grpc_e2e_performance_* tests.
Example failure: https://source.cloud.google.com/results/invocations/2112f2d5-db91-4901-87cb-cc9865f351f1/targets
The daily performance test passes with this fixit branch:
http://sponge2/23d4df20-f4dd-48ee-8789-4cd96b078ed5.
Additional fixes:
reorder imports according to the google style guide
replace deprecated cgi.escape library method with html.escape
In case it comes up, with respect to upgrading from py2 to py3, the iter{items,keys,values} methods are intentionally replaced with the less-efficient-in-python2 non-iter versions. This is a recommended practice even when supporting both python versions, and this is not performance-critical code.
Additional note: there is no performance difference btw py2 and py3 (~80 minutes to finish)
