* Add static analysis to hack/verify-govet-levee.sh for defense against
accidental logging of credentials.
* Add binary dependency to hack/tools/tools.go and associated go.mod, go.sum.
* Add analysis configuration to hack/testdata/levee/
- add ./hack/tools/go.mod, this makes ./hack/tools a distinct module
- hack/tools/tools.go undescore imports bazel related tools, over time we
can add others.
- hack/*.sh scripts will cd to hack/tools and go install tools from there
