`failure_count_threshold`: We should never need this, but we don't
want to block access in tests because of this.

`failure_wait_time`: Setting it to 0 now allows each storage attempt

`storage_timeout`: Try a bit longer to access storage on CI in case
the slow machines take a bit longer to spin up the process to perfom
the check

This allows testing every storage attempt after a failure. Which could
be useful for tests
