Add benchmarking

[gaurav]

It would be great to have benchmarking to check the speed of a set of queries and to load-test NameRes instances.

Possible options:

• https://predator.dev
• GitHub Actions

We do have the NodeNorm/NameRes/Babel validation sheet, which we could use to set up and test integration tests. Note that that spreadsheet can include failing tests currently in development.

We have some basic speed tests in development at TranslatorSRI/babel-validation#27
We also now support Jaegar instrumentation to look at how quickly NameRes works on ITRB: #121

This ticket still covers figuring out how to automate this, run it regularly and report the findings.
