Avi Kivity 2482e53de9 test: alternator: configure scylla for test environment in terms of cpu and disk
Currently, the alternator tests configure scylla to use all the
logical cores in the host system, but only 1GB of RAM. This can lead
to a small amount of memory per core.

It also uses the default disk configuration, which is safe, but can be
very slow on mechanical or non-enterprise disks.

Change to use a fixed --smp 2 configuration, and add --overprovisioned
for maximum flexibility (no spinning). Use --unsafe-bypass-fsync
for faster performance on non-enterprise or mechanical disks, assuming
that the test data is not important.

Fixes #6251.
