tests: Use ThreadedMotoServer python class to launch mock S3 server (#9313)

Browse Source 
This is simpler than using subprocess.

One difference is in how moto's log output is now collected. Previously,
moto's logs went to stderr, and were collected and printed at the end of
the test by pytest, like this:

Note the timestamps: the timestamp at the beginning of the line is the
time that the stderr was dumped, i.e. the end of the test, which makes
those timestamps rather useless. The timestamp in the middle of the line
is when the operation actually happened, but it has only 1 s
granularity.

With this change, moto's log lines are printed in the "live log call"
section, as they happen, which makes the timestamps more useful:
