[QA-EE] Toggle Gitaly N+1 detector via feature flag and run tests

See merge request gitlab-org/gitlab-ee!10324

First attempt at allowing a feature flag to be set via the command line
when running tests. This will enable the flag, run the tests, and then
disable the flag.

Using OptionParser meant changing how scenarios get the instance
address, so this also allows the address to be set as a command line
option. It's backwards compatible (you can still provide the address
as the command line option after the scenario)
