feat: sentry fastapi integration added

[sambarnes]

Details

todays warmup ☕ we had sentry on the completion container startup, but nowhere else in the runner

now, any exception that causes an Internal Error will report up to sentry (behavior can be found in the docs here) and all new endpoints are auto instrumented with it

e.g. i deployed this endpoint to dev & it bubbled up to sentry here

@api_app.get("/foo")
async def foo():
    return 5 / 0

ngl not a fan of having to put these deps in .pip_install blocks everywhere & duplicating what a pyproject.toml should do :/ a little hard to reason about what packages are allowed to be imported & in what scopes (but seems like just a modal limitation)

i think when @montasaurus adds the ddtrace package, it might make sense to consolidate some of this dependency boilerplate with a func that takes in a modal.Image and chains in the .pip_install( for sentry+ddtrace+other common observability things

at least keep it in a single spot in our python

Got exactly that in a PR I'm working on!
