Vlad Lazar df6909302b test: add benchmark for tenants with large slrus 
The new bencmark generates tenants with around 300 SLRU blocks
of 8KiB each. Both vectored get implementations are benchmarked.
For the vectored implementation validation is disabled.

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.
