John Spray 89cf714890 tests/neon_local: rename "attachment service" -> "storage controller" (#7087) 
Not a user-facing change, but can break any existing `.neon` directories
created by neon_local, as the name of the database used by the storage
controller changes.

This PR changes all the locations apart from the path of
`control_plane/attachment_service` (waiting for an opportune moment to
do that one, because it's the most conflict-ish wrt ongoing PRs like
#6676 )

How to reproduce benchmark results / run these benchmarks interactively.

  1. Get an EC2 instance with Instance Store. Use the same instance type as used for the benchmark run.
  2. Mount the Instance Store => neon.git/scripts/ps_ec2_setup_instance_store
  3. Use a pytest command line (see other READMEs further up in the pytest hierarchy).

For tests that take a long time to set up / consume a lot of storage space, we use the test suite's repo_dir snapshotting functionality (from_repo_dir). It supports mounting snapshots using overlayfs, which improves iteration time.

Here's a full command line.
