Brandon Simmons a3fc1889bb benchmarks: add an initial adhoc operation mode, suitable for benchma…
…rking metadata operations

And add an initial benchmark for replace_metadata, to unblock some
performance improvements to that op in a PR to be merged after this.

This is an MVP just to have something in CI to reference when optimizing
metadata operations. See TODO for roadmap.

Run hasura benchmarks
Usage:
$ $0 <benchmark_dir> [<hasura_docker_image>] [<sleep_time_sec_before_bench>]
The first argument chooses the particular benchmark set to run e.g. "chinook"
or "big_schema" (these correspond to directories under 'benchmark_sets/').
The second optional argument is the docker image name to test. e.g.
"hasura/graphql-engine:latest" If omitted we'll look for a hasura instance
launched with 'dev.sh graphql-engine'.

# - EBS is incredibly finicky and difficult to provision correctly[1]; we

# - SQL-gen regressions should still show up as regressions if we're backed by
# tmpfs; only perhaps the magnitidue would change. We also expected PG to be
# doing significant in-memory caching on the small datasets here.
# - There is some evidence[2] that ramdisk is actually a decent approximation of
