Remove the bin/dwh-migration-client script, as the executable it referred to no longer exists

[arotenberg-google]

The docs on the GCP site and the bin scripts included in the release zip refer to an executable named dwh-migration-client, but that command doesn't exist anymore, there's only run.sh and bqms-run.

There will need to be a separate Google-internal change to update the GCP docs.

The current behavior of the client on a clean pip install can be confirmed using this Dockerfile:

> whereis dwh-migration-client
dwh-migration-client:
> whereis bqms-run            
bqms-run: /usr/local/bin/bqms-run

Should we update the code to match the docs, or the docs to match the code? dwh-migration-client is a better name than run.sh

Both run.sh and bqms-run are admittedly bad names. I am not good at naming ;-).

If we exchange $SCRIPT_DIR (defined here) for $PWD then we should be able to pull run.sh into a top-level bin directory as long as $PWD contains input and config dirs. And of course we can rename run.sh as well and update the docs.

clean.sh and deprovision.sh are trivial and could just be deleted. provision.sh shows all of the gcloud commands you would need to run if you were starting from zero without a project and needed to provision the correct resources to run locally or on Cloud Run. It is truly meant as an example as no one really uses a bash script with gcloud commands as a devops tool. I created it simply to spin up demo environments from scratch and as executable documentation. Not sure where that belongs, if anywhere.
