golang: add CRDB to golang benchmark suite

[herkolategan]

We have the opportunity to add CockroachDB to the Go benchmark suite [2], similar to etcd. This would yield many benefits for both us and golang. See this discussion [2] that led to the suggestion.

[3] Would be a good starting point to use as an example of how a benchmark was recently added to the suite.

This issue is just a starting point and placeholder for now, there is more internal info related to some of the mechanics of the suite.
