pokeeffe-molecula a1fc6d04a1 introduce performance counters and system table fanout, plus refactor metrics (#2363 )

* performance counters

* first cut of perf counters and system table fanout and a wire protocol
* significantly refactored prometheus support; removed statsd and exprvar

* removed node_id

* put dax subquery test back

* Change Translator.TranslateFieldIDs method to take a dax.TableKeyer

There are a bunch of other calls to the Translator interface methods
with currently take an `index string`, and those need to be converted to
dax.TableKeyer as well. But I need to review each call, because in at
least one place I noticed one being called with `result.Index` instead
of with the qtbl available. And I don't yet know how those could be
different.

DAX

DAX encapsulates anything which covers all of the services which make up the "disaggregation of storage and compute" project. Initially, this will include integration tests which pull in things like Metadata Services (MDS), including the Controller, as well as FeatureBase and IDK-based ingesters.

Setting up the tests

The DAX test currently requires docker images for: featurebase and datagen.

If at any point you run into problems with go mod failing to reference a private repo, make sure that you have gitlab.com/featurebasedb in your GOPRIVATE environment variable.

Note that during the docker image build step, go mod vendor is run, which creates a vendor directory in the root directory, and copies that to docker during the build stage. Just be aware of this; you may want to remove that vendor directory after you're done building docker images.

Possible Configuruation

The following were relevent when the dax code was in a separate repository. These may no longer be relevant.

I needed to but this in my ~/.profile file:

export GOPRIVATE=github.com/featurebasedb,gitlab.com/featurebasedb

And this in my ~/.gitconfig

[url "ssh://git@github.com/"]
	insteadOf = https://github.com/
[url "ssh://git@gitlab.com/"]
	insteadOf = https://gitlab.com/

Then make docker ran successfully.

Build the FeatureBase docker image

Check out the dax branch of the featurebase repository.
Run make docker-image-featurebase to build the docker image
You should now have an image in docker named dax/featurebase with the tag latest.

Build the Datagen docker image

cd <featurebase_repo_root>/idk
Run make docker-image-datagen to build the docker image
You should now have an image in docker named dax/datagen with the tag latest.

Running the tests

Check out the dax branch of the featurebase repository.
Change into the dax directory: cd dax
Run make test-integration.
