I've been wondering whether it might be a good idea to expose more 
worker options in the config file.
I wrote some patches that expose the following options:

- s3-location: allows the s3 storage location to be changed
- max-artifacts: allows the maximum s3 artifact count to be changed
- max-artifact-size: allows the maximum artifact file size to be changed
- startup-timeout: allows the worker-startup timeout to be changed (as 
initially proposed)

The names aren't final yet, and I haven't had the chance to test the 
patches. (My new server is faster than the old one and able to start 
the workers within the 2-minute default, and I don't know enough about 
minio to validate the server location)

I've set up my personal sourcehut instance with build.sr.ht.
However, my sourcehut builds kept failing (they won't even start):
 > [#14] 2023/11/04 19:10:53 Booting image alpine/edge (default) on 
port 22113
 > [#14] 2023/11/04 19:10:53 Waiting for guest to settle
 > [#14] 2023/11/04 19:12:53 Error: Settle timed out after 3 attempts

After looking at the worker source code,
I noticed that the settle timeout is hard-coded to 120 seconds [1].
Because it is hard-coded, I had to rebuild the worker and replace the
binary to change it (5 minutes did the trick, because it takes about 2 
1/2
minutes to spin up).
