Turn on profiling when FLASK_PROFILE=True

[esheehan-gsl]

I am finding myself having to profile the application from time-to-time to manage performance, so I think it makes sense to have the ability to just add the profiling middleware using an environment variable flag.

Package	Line Rate	Branch Rate	Health
unified_graphics	80%	68%	➖
unified_graphics.etl	97%	96%	✔
utils.s3	68%	69%	➖
Summary	84% (369 / 437)	81% (86 / 106)	✔

Minimum allowed line rate is 60%

That's really handy to have that middleware! Looks good to me.

I wanted to confirm I understood what the restrictions=[30] statement does - it looks like it restricts the middleware to print out the top 30 calls. Is that correct?

I think that’s correct, but I haven’t experimented with that argument to see how it affects the output. I have used this set up a couple of times to identify and fix performance issues, and since it has worked and this bit only ever runs in development with the debug server on and the profiling env variable set (and thus it should never run in production), I haven’t worried too much about what it does. 😅

Gotcha. That's good enough for me then! 😁
