Add flag to run without building baked images.

Adds flag to :benchmarks to allow running without
building "baked images", which depends on gcloud.

Users can skip gcloud workflows using the following:

blaze run --define gcloud=off :benchmarks -- my-command-without-gcloud

"run-gcp" will not work with the flag set, but all other commands will.
