rely on sdk default for most requests

[sssoleileraaa]

Description

Increase the timeouts to rely on the sdk's default of 20 seconds for any requests that we agressively killed after 5 seconds until we gather more staging/prod data on how long each request takes, see #648. We also are continuing to discuss the value of increasing the timeout each time a job retries until it runs out of retries.

What the subprocess timeouts will be after #1055 and this PR are merged

Endpoint	SDK subprocess timeout
get_sources	60
get_all_replies	60
get_all_submissions	60
reply_source	20
add_star	20
remove_star	20
delete_source	20
authenticate	60
logout	60

Test Plan

Make sure there are no regressions.
