Switch to Go modules to manage dependencies

As was planned for some time, `dep` was officially deprecated and its repository was archived this last week. There may some more work to do with the PGOROOT variable in Makefile and elsewhere. The following commands where used to make this transition: go mod init github.com/crunchydata/postgres-operator sed -i '' -e 's,gopkg.in/robfig/cron.v3,github.com/robfig/cron/v3,' \ ./go.mod ./pgo-scheduler/*/*.go go mod tidy rm -r vendor Gopkg.* Co-authored-by: Jonathan S. Katz <jonathan.katz@crunchydata.com> Issue: [ch9453]

-The project uses the golang dep package manager to vendor all the golang source dependencies into the `vendor` directory. You typically do not need to run any `dep` commands unless you are adding new golang package dependencies into the project outside of what is within the project for a given release.

 After a full compile, you will have a `pgo` binary in `$HOME/odev/bin` and the Operator images in your local Docker registry.
