Automated benchmarks

Terraform scripts to run on demand and a subset of connectors. Sets up a benchmark. Runs X number of records through the database to see if we

Not every permutation of connector and database but close ;-)

Benchmarks for the internals of conduit.

Types:
1. Integration Benchmark - Useful for end users.
2. Unit Benchmarks - These are useful for us.

Start by identifying the Terraform entry points, supported connectors, and database targets needed to run benchmarks on demand. Define how integration benchmarks for end users differ from unit benchmarks for Conduit internals, and document what record counts, connector/database coverage, and successful results should be measured.
